It was created by necking down the 7×57 Mauser case to the 257 bullet size. ), 265 yard KPS = 15.9 (Energy = 1235 ft. VG condition. The .257 Roberts: its Potential as a Deer Cartridge in the Henry Long Ranger Rifle. The only watch-point for the Hawkeyes in .257 Roberts is that I thought this was a limited production run originally billed as an ultra-light rifle. However, for milder cartridges, such as the .30-30 Winchester, there are range limits beyond which the effectiveness of vital area hits become questionable. Fortunately, there is a reasonably straightforward way to do this. (20 inch barrel), ME 1943 ft. (22 inch bbl. Close up of Pronghorn Antelope on VZ 24 Mauser floorplate. Although, as stated previously, Remington no longer makes a .257 Roberts, you can still find them in the model 760 at gun shows. In each data set, the first line lists information about the load. Therefore, KPS numbers generated from different data inputs (E, SD, or A) are directly comparable. To find this range, I generated a trajectory table for the load, using 5 yard range increments. As it turned out, the .257 Roberts was chosen because I had obtained a rifle about a year earlier. Specifically, I hope that Henry Repeating Arms Co. (www.henryusa.com) will chamber their new Long Ranger lever action rifle in .257 Roberts. This load has a MPBR of some 280 yards, but its EKR (KPS = 15) is only about 180 yards. at a range of 180 yards. Thus, HITS scores are keyed to that distance. Hopefully, this process will become clear after we look at some data. The point is that KPS and Effective Killing Range can be very useful tools for shooters who want to evaluate the killing performance of different cartridges and loads. ), 200 yard KPS = 18.4 (Energy = 1360 ft. load detailed above is a very strong one. Assuming a field ready weight (rifle, scope, sling and cartridge load) of 8.5 pounds, the recoil of the Long Ranger rifle would fall between 9.0 and 10.0 ft. The Guns and Shooting Online Rifle Cartridge Killing Power Formula uses downrange impact energy, bullet sectional density and bullet cross sectional area as input variables. (Not quite the same range, but very flat shooting.) lbs., MPBR = 265 yards (zero at 225 yards). Basically, he necked down the 7x57mm Mauser case to take .257 inch diameter (standard .25 caliber) bullets. ), 100 yard KPS = 22.0 (Energy = 1631 ft. The Roberts is not a puny quarter-bore cartridge! This translates to an effective killing range of 175 to 180 yards. My own nostalgic 257 Roberts was chambered in the 1983 Remington Classic Model 700 rifle. Too many other calibers available that exceed the performance of the .257. The KPS formula makes a lot of sense to me. (Assuming a +1.5 inch line of sight.) (The cross-sectional area of a .257 inch diameter bullet is 0.0519 sq. The .243 Win. It balances between the hands and points naturally. Remington went on to offer this chambering in the Model 722 bolt action and the Model 760 pump action. The .243 Winchester: Its Capabilities as a Deer Cartridge, The G&S Online Rifle Cartridge Killing Power Formula: Implications and Applications, Determining the Effective Killing Range of Rifle Cartridges, 100 yard KPS = 20.7 (Energy = 1602 ft. Bullet velocity is not neglected, because velocity is the most important factor in calculating kinetic energy. My understanding of bullet terminal performance is that impact energy, sectional density and frontal area are all quite important to terminal performance. Therefore, my main task here is to sell the proposition that the .257 Roberts is a better Class 2 game cartridge than the .243 Winchester. .243 Win. (20 inch barrel), ME 2103 ft. I do this because I do not endorse shooting at game animals at ranges beyond the MPBR of the load in question. To summarize, the .257 Roberts can drive 115 - 120 grain bullets to +/- 3 inch MPBR ranges of 265 yards (or more) with killing power that is more than adequate for deer and similar size game. This was 1346 ft. lbs. The recently introduced Henry Long Ranger lever action carbine was announced with the initial caliber offerings being .223 Remington, .243 Winchester and .308 Winchester, with more calibers promised in the future. The .257 Roberts cartridge does not deserve to be shoved into obscurity. (22 inch barrel), ME 2162 ft. lbs. In a short action, it has the potential for a suitable youth rifle but without care towards optimizing hand loads, can lack the power with many 117 to 120 grain loads to be of any great advantage over the more common .243. lbs., MPBR = 265 yards (Zero at 225 yards). The commercial Remington version of the .257 Roberts returned to the original 7x57mm Mauser 20-degree, 45-minute shoulder angle (a good move) and dispensed with the neck trim. Any advantage the 243 has is only on paper. The ballistic performance based off four grain types for velocity are … I mentioned earlier that the .257 Roberts has a reputation for being a mild shooting cartridge. That is well beyond the MPBR of the load. (Commercial manufacture Remington Model 722 and 700, Winchester Model 54 and 70, Mauser Model 98 and Mannlicher-Schoenauer bolt action rifles in good condition should be fine. All I will say is that anyone who has a .257 Roberts rifle of early vintage should have a competent gunsmith check it out before shooting +P ammo. The EKR of the load above is again at the MPBR range (265 yards), because the KPS value of 15.9 at 265 yards is greater than the baseline KPS of 15. However, the .243 Winchester cannot match the .257 Roberts as a big game cartridge, although the .243 is arguably a more efficient heavy varmint round. (SD is the ratio of a bullet's weight in pounds to the square of its diameter in inches.). My example is a Federal Premium .243 Winchester load with a 100 grain soft point spitzer bullet. ), SD .226, A = .0745 sq. ), .243 Win: Federal 100 gr. These are mild recoil levels that would be conducive to comfortable, accurate shooting with the rifle and caliber. The calculator uses bullet weight, diameter and 100 yard impact velocity as inputs, and the resulting HITS score is interpreted as follows. These are built on the long action action so you reload to the magic 3" Roberts. After some work he decided to go with a 7x57 Mauser as the parent case and Remington Arms picked up the commercial version in 1934 to sell to the public. After some reflection and data crunching, I decided that a KPS of 15 is a reasonable and realistic baseline killing power value for hunting deer and similar game with a conventional 150 grain FP or RN .30-30 load. from a 24 inch barrel. I did some estimates of recoil with the heavy hunting loads I have featured. The KPS formula combines these variables in a direct, easy to calculate way. E = KPS / (SD x A) = 15.0 / .0112 = 1339 (ft. 1-2 shots and done. The 257 Roberts — Go for a Nostalgic Hunt. (I adjusted this to a more normal 22 inch barrel length for a .243 hunting rifle. (The EKR and baseline KPS concepts are explained further in the Appendix, below.). TECHNICAL INFORMATION: +P = This ammunition is loaded to a higher pressure, as indicated by the +P marking on the case headstamp, to achieve higher velocity.Use only in firearms especially designed for this cartridge and so recommended by the manufacturer. I call this the "baseline" KPS value for deer cartridges and loads. Those who reflect on the decline of the .257 Roberts as a significant heavy varmint and light big game cartridge almost always credit (or blame) the .243 Winchester. (20 inch bbl. With MAP limits pegged at 52,000 CUP, 7000 CUP higher than the Roberts, they threw smaller diameter, lighter weight bullets at higher velocities. Using deer and similar size game as an example, some popular cartridges, such as the .270 Winchester and .308 Winchester, are so powerful that there is no question that they will dependably fell Class 2 game out to their MPBR range or beyond. guarantee I put a full-size 2.5-10X 50 mm Zeiss Victory HT with 30 mm tube on the rifle. Factory ammo can still be found, especially if you shop fully-stocked gun stores or gun shows. Winchester - Model 70, .257 Roberts, 24” barrel, claw extractor bolt action rifle, 1949 manufacture date, metal is in 99% condition, perfect bore showing very little if any, use, w... (read more) Gun #: 978363034 The resulting MPBR (265 yards) gave me an unambiguous measure of the practical range of the load. Get SPECIAL OFFER and cheap Price for 257 Roberts Rifle Reviews And Ar 15 Hunting Rifle Reviews. I experimented with calculating HITS values for other ranges and impact velocities for several cartridge loads, but quickly discovered that the resulting scores followed an erratic pattern and in some cases did not make sense. 257 Roberts could do very well with a 24" barrel for a lot of reasons. It is clear that the .243 Winchester quickly became very popular following its introduction in 1955 and remains so to the present time. The rifle was a Winchester XTR Featherweight that became available through a strange set of circumstances. The introduction of DuPont Improved Military Rifle Powder Number 4350 in 1940 – at the time, the slowest burning powder available to handloaders – really did improve velocities in many centerfire cartridges, including the .257 Roberts. Wrong! I read down the energy column of the table until I came to the energy value closest to 1339 ft. lbs. Load #3 features a 120 grain bullet, the heaviest hunting bullet loaded in the Roberts. I don't think the .257 will ever make a strong re birth. However, before Henry could justify offering the Long Ranger in .257 Roberts, they would have to be convinced that hunters would buy it. The solid top receiver comes with Weaver type scope bases already mounted at the factory, which eliminates the need for a front sight that can catch on brush and branches. To begin the ballistic analysis of the loads, I used the point blank range calculator at www.shooterscalcualtor.com to calculate a +/- 3 inch maximum point blank range (MPBR) for the load. Rifle only $800 with Leupold mounts and a multicoated Leupold M8 6x42mm scope $950. ", "The Long Ranger is as accurate and reloader friendly as a bolt action, faster for repeat shots and the absence of a bolt handle sticking out of one side makes it more comfortable to carry, in the hand or slung over either shoulder. -Editor). Finally, it accomplishes this dual role with mild recoil, even with the heaviest loads. .257 Load #1: Nosler Custom, 115 gr. Discussing this issue in detail is outside the scope of this article. Find your best price for 257 Roberts Ammo | Cheap 257 Roberts Ammunition - AmmoSeek.com Search Engine 2020 Note that the HITS calculator uses 100 yard impact velocity as an input variable. (20 inch barrel), ME 1862 ft. This capability is important in ways I will demonstrate. The .257 Roberts, also known as .257 Bob, is a medium-powered .25 caliber cartridge.It has been described as the best compromise between the low recoil and flat trajectory of smaller calibers such as the .22 and 6mm, and the strong energy but not the strong recoil of larger popular hunting calibers, such as the 7mm family and the popular .30-06. (Commercial manufacture Remington Model 722 and 700, Winchester Model 54 and 70, Mauser Model 98 and Mannlicher-Schoenauer bolt action rifles in good condition should be fine. Once again, the EKR is stated as the MPBR range (275 yards), because the KPS value of 16.9 at 275 yards is greater than the baseline KPS of 15. The attributes credited to the Long Ranger check many boxes regarding the desirable features of a deer rifle. lbs. A Glock in the Pocket, Worth Two in the Safe. Interlock RN, MV 2350 f.p.s. The 257 Roberts is one of two .25 caliber cartridges used for daily production testing in the Nosler Ballistics Lab. The .257 Roberts is a low recoiling, mild powered cartridge. The Hornady H.I.T.S. lbs.). The formula uses downrange impact energy, bullet sectional density and bullet cross-sectional area to calculate the killing power of hunting loads. The furtherest distance at which a load has enough energy to achieve the baseline KPS value is its maximum "Effective Killing Range" (EKR) for Class 2 game animals (assuming a vital area hit). Unless you want one for nostalgia, I would go to something else. classification system uses an online calculator to produce a numerical HITS score for rifle cartridge loads. Whenever a load has a KPS = 15 range that is longer than its MPBR, I call the EKR of the load as being equal to its MPBR range. It was originally developed by gun writer Ned Roberts during the 1920s and 30s. Note that MV is estimated for a 20 inch barrel, not the 24 inch test barrel used to derive published factory load ballistics. .257 Load #3: Federal Vital-Shok, 120 gr. I feel this even more strongly after making a detailed examination of the performance and capabilities of the cartridge. The .257 was very popular in the '50's and in Inlet, N.Y. a guy killed a 400+ bear just outside of town with one shot from a .257. (The .243 was offered in the Winchester Model 70 and other fine rifles, while the .244 was offered in the clunky Remington Model 722.) These cartridges were highly touted by Warren Page, the Shooting Editor at Field & Stream magazine, and appeared to be ballistically superior to the .257 Roberts. lbs., MPBR = 300 yards (Zero at 255 yards). lbs. At the Orvis flagship store in Manchester, Vermont, I found a brochure at the counter highlighting the rifle. (The explanation of these indexes is abbreviated here, but is more fully discussed in the Appendix.). 22lr Winchester Rifle And 257 Roberts Rifle Manufacturers Reviews : If you're looking for 22lr Winchester Rifle And 257 Roberts Rifle Manufacturers. Thus, the 100 yard KPS of this load is: This is merely an example, as KPS can be calculated for any range. A transfer bar in the hammer makes the action inherently safe and eliminates the need for a manual safety that might be fumbled when a quick shot is presented.". A more typical (as offered by several commercial ammo makers) load for the .243 features a 100 grain bullet at 2920 f.p.s. I chose 20 inches, because the Henry Long Ranger rifle has a 20 inch barrel. MPBR and zero distances are rounded to the nearest five yards. If you walked into your favorite local gun shop or hunting supply store and did not find 257 Roberts ammo on the shelf, I would not be shocked either. It has an even more nostalgic Redfield scope mounted on it. I realize that setting a KPS of 15 as a baseline power standard for the .30-30 load is a judgment call, but I am comfortable with it. : Doubletap 100 gr. load falls 25 yards short of its MPBR. First, like others in the hunting fraternity, the rifle was the main draw. lbs., depending on the load in question. In the 1980s more power was loaded in this cartridge, when ammo makers brought out +P loadings. Fully engraved American scroll grip cap on .257 Roberts custom VZ 24 Mauser. All of the .257 Roberts loads listed above blow this .243 load away. I have Game Master 760's in .300 Savage and .257 Roberts. That said, I will simply refer to the cartridge and rifles chambered for it as ".257 Roberts" hereafter. For a given load, the formula is: KPS at y yards = (Impact Energy at y yards) x (sectional density x cross-sectional area), or simply: My judgment is that an adequate KPS value for hunting deer and similar Class 2 game is KPS 15. ), 265 yard KPS = 16.2 (Energy = 1203 ft. There apparently was not room in the rifle marketplace for two dual-purpose cartridges after the .243 Winchester was introduced and it bested the .244/6mm Remington, .250 Savage and .257 Roberts in the popularity contest, for whatever reasons. The .243 cartridge/load, being faster, must be better, right? .257 Load #2: Hornady Superformance, 117 gr. in. ), 100 yard KPS = 23.2 (Energy = 1771 ft. Detachable, steel sling swivel studs and a contoured, effective recoil pad are standard equipment. If you searching to test 22 Marlin Rifle Magazines And 257 Roberts Rifle Manufacturers price. However, the comparison is not quite that simple. Remember, this is from rifles with 20 inch barrels. Whenever any of these variables change, the KPS number changes proportionally. Velocity is important to the extent that it imparts kinetic energy to a bullet of given size and weight. Next, I developed a trajectory table for the load using the ShootersCalculator trajectory calculator. HITS scores at 100 yards for the .257 loads are 718 (Load #1), 773 (Load #2) and 772 (Load #3). lbs., MPBR = 275 yards (Zero at 235 yards). Having used both the 257 Roberts and the 243 for deer, I would choose the Roberts in a heartbeat over the 243. Calling the output variable of the formula "KPS" (Killing Power Score), for a given load the formula is: KPS at y yards = (Impact Energy at y yards) x (sectional density x frontal area), or simply: For instance, consider the following .30-30 Winchester factory load: Hornady 150 gr. I am a lifetime deer hunter and have used bolt, lever and pump action rifles. The hottest commercial .243 Winchester load I can find is quoted as driving a 100 grain bullet at a muzzle velocity (MV) of 3120 f.p.s. Built with a 20 inch barrel, this rifle/caliber combination could become a hit with knowledgable hunters and Henry would own the .257 Roberts rifle market. For sale 1982 Remington 700 Classic 257 Roberts. Copyright 2017 by Gary Zinn and/or chuckhawks.com. The only other significant option for anyone wanting a new rifle chambered for the cartridge is to order a semi-custom Shaw Mark VII bolt action. My hope is one of these will be the .257 Roberts. I do use the +P WW brass. Finding a rifle in the Roberts might take some doing, but the search would be worth it. I am only stating what the numbers show. Performance of modern .257 Roberts factory loads. Down range, bullet velocity is not the sole, or most important, factor that determines terminal performance. SST bullet, BC .390, MV 2845 f.p.s. The .257 was designed to run in a bolt gun, and any receiver that was designed for the 7x57mm Mauser will handle the .257 Roberts perfectly. (Hornady HITS is explained in the Appendix.). The .257 Roberts was the premier combination varmint/deer cartridge until the .243 Winchester and .244 Remington were introduced in 1955. Much later Remington added it in their limited once-a-year 700 Classic line. lbs. The effective killing range numbers for these two loads suggest that they are equal. Fellow SIG Fans: Has the P320 Drop Test Scandal Soured You On SIG? The result means that the KPS of the load in question will be equal to 15.0 at the range where the energy of the bullet falls to 1339 ft. lbs. Hornady HITS scores for .257 Roberts and .243 Win. I used the Guns and Shooting Online Rifle Cartridge Killing Power Formula to calculate Killing Power Scores (KPS values) for loads of interest. Pre 64 Model 70 Winchester Rifles For Sale And Remington Model ), 200 yard KPS = 17.7 (Energy = 1371 ft. in.) (22 inch barrel). This comparability can be applied not only to different loads for a particular cartridge, but also can be extended to comparisons of different cartridges. lbs. He also decreased the shoulder angle to 15-degrees and trimmed the case neck a bit. I have not used any factory ammo in the Roberts but I load the 100 Grain X bullet to 3050 fps. Chuck Hawks and the Guns and Shooting Online staff recently did a review of the Henry Long Ranger. The 257 Roberts cartridge has a very interesting and curious history. lbs. See The G&S Online Rifle Cartridge Killing Power Formula: Implications and Applications and Determining the Effective Killing Range of Rifle Cartridges for fuller discussion of the killing power formula and effective killing range concepts. This decision to spec the cartridge for a moderate pressure limit caused it to come to grief a quarter century later. For instance, between 100 and 175 yards, the energy of the 150 grain .30-30 bullet decreases by 27.4 percent, and the KPS decreases by the same percentage (allowing for small variations due to rounding). The remaining (bullet pointed) lines summarize the results. ), 275 yard KPS = 16.9 (Energy = 1292 ft. The 100 yard HITS score for the strongest .243 Win. Note that the EKR of the .243 Win. ), 275 yd.

It is truly a hunting rifle i.e. By comparison, the fastest heavy bullet .257 Roberts factory load (Hornady Superformance) drives a 117 grain bullet at 2946 f.p.s. It was created by necking down the 7×57 Mauser case to the 257 bullet size. I rest my case that the .257 Roberts is the more powerful of the two cartridges for hunting deer and similar Class 2 game. ), 100 yard KPS = 20.4 (Energy = 1826 ft. Compare prices for Ruger 22 Long Rifle Automatic Pistol Serial Numbers And Ruger 257 Roberts Rifle For Sale You can order Ruger 22 Long Rifle Automatic Pistol S lbs. This Model 70, along with most rifles chambered for the .257 Bob, are made with 22-inch barrels. lbs. Hunters, in turn, would need to be convinced that the .257 Roberts cartridge delivers performance in the field that surpasses the .243 Winchester, which is already being offered in the Long Ranger rifle. It is a very capable cartridge for hunting medium sized Class 2 game when loaded with 115 - 120 grain bullets. I would not be surprised if many of you deer hunters and rifle enthusiasts ever even heard of this cartridge or knew much about it. Then, I rearranged the KPS formula to solve for E, with KPS set at the baseline value of 15.0 and (SD x A) = .0112 for the 100 grain .243 bullet. ), BC .355; (SD x A) = (.242 x .0464) = .0112. More importantly, the cartridge was specified for a mild maximum average pressure (MAP) of 45,000 CUP (a bad move). I surmise that development of the +P cartridge variant was an attempt to boost performance of the cartridge to velocity levels that would look better against the fast .243s. Loads with 95 and 90 grain bullets have EKRs of 205 and 175 yards, respectively. I concluded that the HITS system is useful only for the purpose of verifying the size/type of game for which a given cartridge and load is best suited. All rights reserved. It is a shame that Remington did not specify the .257 Roberts for a MAP of 50,000 CUP in the first place. Firearms experimenter Ned H. Roberts created what was to become the .257 Roberts commercial cartridge during the mid-1920s. Thus, 180 yards is the Effective Killing Range of this load. Cartridge Type: Rifle Height: 2.233" Width: 0.473" Average FPS: 2790 Average Energy: 2039 Average Gr: 118 Recoil: 1.47 Power Rank: 3.29 of 20 The .257 Roberts was designed in the 1920s when wildcatter Ned Roberts started to do experiments on the .257 caliber cartridges. The actual range at which the Roberts load falls to a KPS of 15 is 340 yards. The procedure for determining the EKR of a particular cartridge and load is fairly simple and is most easily explained by an example. The Roberts .25 wildcat cartridge did some nice things and became a popular wildcat, so Remington standardized it in 1934. All I will say is that anyone who has a .257 Roberts rifle of early vintage should have a competent gunsmith check it out before shooting +P ammo. However, factory .257 ammunition continued to be loaded to 1930’s velocities until almost 1990. Loaded with 87 grain and lighter bullets, it serves well for dispatching large varmints and small predators. (All three of the .257 Roberts loads have KPS = 15 ranges that are longer than their MPBR distances.). Shipped in a hard case. Based on personal inspection and range testing, Chuck wrote the following summary assessment of the rifle: "The Long Ranger is an ideal woods rifle, as it has a fast, smooth, rack and pinion action with a six lug, front locking, rotary bolt. Swift Scirocco II, BC .384, MV 3120 f.p.s. To my knowledge, the only currently available .257 Roberts production rifle is the Kimber 84M Hunter bolt gun. Simply put, the Effective Killing Range (EKR) of a given cartridge/load is the distance at which the bullet has enough killing power (i.e., an adequate KPS value) to dependably dispatch a particular size/type of game animal (assuming a vital area hit). This load produces 1232 ft. lbs. hunting loads tell the same story. BT bullet, BC .459, MV 2700 f.p.s. ), 200 yard KPS = 19.4 (Energy = 1483 ft. KPS = 15.0 (Energy = 1339 ft. Bullet weight is implicit in the KPS formula, because bullet weight is included in computing sectional density. I used two-piece mounts, fairly light, but in order to give the rifle its best chance to meet its sub-m.o.a. If you searching to check on 257 Roberts Rifle Ammo For Sale And 270 Winchester Ammo Australia price. What if .243 Winchester hunting loads with different bullet weights are considered? This is a standard 100 grain .243 Winchester factory load at a MV of 2960 f.p.s. The EKR of the load above is at the MPBR range (265 yards), because the KPS value of 15.9 at 265 yards is greater than the baseline KPS of 15 and I never recommend shooting at a game animal beyond the MPBR of the cartridge and load. Once again, here is the strongest .257 Roberts factory load, as detailed above. My purpose here is to propose (or plead for) a resurrection of the .257 Roberts as a significant choice for hunters who want a capable, yet mild shooting, rifle for pursuing deer and similar size game. The hottest .243 Winchester factory load I was able to identify for the article The .243 Winchester: Its Capabilities as a Deer Cartridge specs out as follows. Remington was the first to commercialize the 257 Roberts in 1934 by chambering their Model 30 bolt action rifle for it. The .257 Roberts is a better deer cartridge than the .243 Winchester. I started with the baseline KPS for the .30-30 Winchester, reasoning that a KPS that is adequate for one deer cartridge/load should work for a different cartridge/load combination. Ruger has also chambered the 257 Roberts in its Model 77 bolt gun, though most other makers have now dropped it from their lineups. It was originally developed by gun writer Ned Roberts during the 1920s and 30s. from a 20 inch barrel. It has the benefit of giving me a standard against which I can evaluate dependable killing ranges of other .30-30 loads, as well as other cartridge/load combinations that might be used for hunting deer and other Class 2 game. From the trajectory table, I recorded muzzle energy and energy at 100 yards and other relevant distances. The next load is the hottest Roberts factory load of which I am aware, driving a 117 grain bullet at an estimated 2845 f.p.s. Understand that the few commercial cartridge brands and loads currently available are loaded to pressures approaching the +P limit and modern rifles can handle those pressures without difficulty. Anyone who disagrees with the baseline KPS I used here may change the analysis to use any cartridge, load and ballistic parameters they feel accurately reflect effective killing power and range, for deer or other game. lbs.
