Why Shooters Choose 257 Roberts Rifle For Sale

Excellent Accuracy and Flat Trajectory

.257 Roberts ammo is known for its flat-shooting nature. It maintains velocity well and drops very little at typical hunting distances. This makes it perfect for shots out to 300 yards and beyond on deer, antelope, and coyotes.

Mild Recoil for Comfortable Shooting

One of the biggest advantages of 257 Roberts ammunition is its gentle kick. It’s easy on the shoulder, which means you can shoot more rounds comfortably — whether you’re sighting in your rifle or spending a full day in the field.

Dynamic Range

For coyotes, like lightning striking. For larger game, 1915 bullet technology probably wasn’t up to that speed. Deer hunters discovered the .250 Savage was more consistent with 100-grain bullets a bit slower. Either way, the .250 Savage was extremely popular.

Well, if a little is good, then more must be better, right? The .25-06 was developed at Frankford Arsenal during WWI. It was able to propel a 100-grain bullet at the magic 3000 fps. However, overbore capacity was an issue, too big a case to efficiently burn the powders of the day. After the war, the .25-06 remained a common wildcat for 50 years.

Still, thanks largely to the .250 Savage, the quarter-bore was an American darling. How about just a little bit more? Instead of the .30-06 case, how about the 7×57 case? Ned Roberts was apparently a perfectionist as a tinkerer. Through the 1920s he worked on various versions, trying to get case capacity just right. His .25 Roberts used a shorter case, created by trimming 7×57 brass. The similar .25 Griffin & Howe used the full-length 2.235-inch 7×57 case. In 1934, Remington’s version also used (almost) the full-length 7×57 case and changed Roberts’ 15-degree shoulder to 20 degrees. Remington dubbed their version .257 Roberts.

Regardless of which version achieved the most perfect capacity and shoulder angle, the 7×57 case solved the .25-06’s over-bore-capacity issue. In 1934, most existing bolt-actions preceded WWI, so from the beginning .257 Roberts factory loads were mild, held to 54,000 psi. They exceeded .250 Savage velocities, but not by much. In those days, serious American rifleshooters handloaded. With handloads in strong actions—’98 Mauser, Springfield, US Enfield, Remington M30, Winchester M54 and later M70—Old Bob strutted his stuff: 90-grain bullet to 3200 fps; 100-grain bullet to 3100 fps; 120-grain bullet over 2800.

Higher Pressure

In the 1980s Remington re-specified the .257 Roberts to higher pressure, a +P loading at 58,000 psi. Common with handgun cartridges, this is the only time this has been done with a centerfire rifle cartridge. Standard +P loadings are: 87-grain bullet at 3200 fps; 100-grain bullet at 3000; 117-grain bullet at 2800. Nothing new for handloaders. Even so, the +P loads generated some new interest in Old Bob. Except: The .25-06 cat was long out of the bag.

By the time the .25-06 Remington became a factory cartridge in 1969, propellants had advanced from the 1920s, better able to utilize the case capacity. The .25-06 runs about 100 fps faster than the Roberts with lighter bullets, and as much as 200 fps faster with 120-grain bullets.

This is significant, although I’m not certain anything from prairie dogs to pronghorns will know the difference…and no .25-caliber is suitable for pachyderms. The .257 Weatherby is faster yet, about the same margin over the .25-06. However, the .25-06 and .257 Wby burn a lot more powder to get there. More heat, friction, and shorter barrel life. Also, more blast and recoil.

Again, it depends on what you want to do. With today’s deep-penetrating bullet designs, the .25-caliber can be stretched to elk-sized game. Mind you, I wouldn’t go elk hunting with any .25, but folks do and can. The .257 was Roy Weatherby’s personal favorite, and I’m told the .25-06 is popular among South African hunters for game up to kudu. For game larger than deer, whether elk or larger African antelope, probably wise to combine bullet weight with as much velocity (and resultant energy) as you can get.
