(20 inch barrel), ME 2103 ft. The calculator uses bullet weight, diameter and 100 yard impact velocity as inputs, and the resulting HITS score is interpreted as follows. I rest my case that the .257 Roberts is the more powerful of the two cartridges for hunting deer and similar Class 2 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. load falls 25 yards short of its MPBR. HITS scores at 100 yards for the .257 loads are 718 (Load #1), 773 (Load #2) and 772 (Load #3). I love the .300 savage for brush country and the .257 rivals my .20-06 in the open. It was created by necking down the 7×57 Mauser case to the 257 bullet size. 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. (The .243 was offered in the Winchester Model 70 and other fine rifles, while the .244 was offered in the clunky Remington Model 722.) I am only stating what the numbers show.

It is truly a hunting rifle i.e. Thus, 180 yards is the Effective Killing Range of this load. Much later Remington added it in their limited once-a-year 700 Classic line. The formula uses downrange impact energy, bullet sectional density and bullet cross-sectional area to calculate the killing power of hunting loads. A Glock in the Pocket, Worth Two in the Safe. For sale 1982 Remington 700 Classic 257 Roberts. 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 remaining (bullet pointed) lines summarize the results. in.) Bullet velocity is not neglected, because velocity is the most important factor in calculating kinetic energy. 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. 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. The Roberts is not a puny quarter-bore cartridge! Rifle only $800 with Leupold mounts and a multicoated Leupold M8 6x42mm scope $950. Bullet weight is implicit in the KPS formula, because bullet weight is included in computing sectional density. Detachable, steel sling swivel studs and a contoured, effective recoil pad are standard equipment. 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. ), .243 Win: Federal 100 gr. 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. lbs.

However, before Henry could justify offering the Long Ranger in .257 Roberts, they would have to be convinced that hunters would buy it. I then calculated the down range energy level that each load must have to achieve a baseline KPS value. The Hornady H.I.T.S. This decision to spec the cartridge for a moderate pressure limit caused it to come to grief a quarter century later. lbs. 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.

Load #3 features a 120 grain bullet, the heaviest hunting bullet loaded in the Roberts. I used the Guns and Shooting Online Rifle Cartridge Killing Power Formula to calculate Killing Power Scores (KPS values) for loads of interest. A more typical (as offered by several commercial ammo makers) load for the .243 features a 100 grain bullet at 2920 f.p.s. 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.
