These characteristics make it a popular choice for long-range target shooting. All I can say is that granting Bob +P status in 1974 was a great kindness. this number for consistency. For reloading I like them for other reasons, and some get lucky, but a person shouldn't expect it. However, before Henry could justify offering the Long Ranger in .257 Roberts, they would have to be convinced that hunters would buy it. The .257 Roberts. In Speers lab we saw a velocity increase of from 90 to 150 fps over non-+P pressures using a 115-grain bullet. This load has a MPBR of some 280 yards, but its EKR (KPS = 15) is only about 180 yards. 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. Most . 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. According to the history Ive read, Roberts worked with F.J. Sage on The .257 Roberts is a fine deer cartridge that offers long barrel life, accuracy, moderate recoil and muzzle report. But for most hunters, ballistics arent the only consideration. hunting loads tell the same story. Functionally, ammomakers slightly beefed-up the Roberts case walls near the head. I cant think of any situation in However, in thumbing through my notes from many years ago, factory loads generally run between 50 and 100 fps slower than claimed velocities when fired from the 22-inch barrel of the Ruger M77R. I mentioned earlier that the .257 Roberts has a reputation for being a mild shooting cartridge. load, detailed above, is 694. experimenting that existing powders of the day would perform much Nothing at all wrong with the Roberts as far as accuracy goes.

The 257 Roberts+P is essentially the same thing as the 25-06 Remington. As a result, I could not find .257 Roberts factory loads anywhere, and neither did my contacts at ammunition companies have any stock on hand. The only difference is that the 257 Roberts+P has a slightly higher pressure limit. Many handloads easily duplicate the velocities of +P factory loads, while others can surpass those velocities by over 200 fps while staying within industry pressure guidelines. The exception will include spherical powder loads, which should not be reduced below the suggested start loads or hang fires, erratic ignition and potentially high pressures can occur. Winchester does not presently list (The EKR and baseline KPS concepts are explained further in the Appendix, below.). to me several months later and was used successfully on antelope the So if you are looking for a fast, versatile round that can handle anything you throw at it, the 257 Roberts should be at the top of your list.
