Coyote Hunter
Perhaps I was too brief and failed to make my point, which is that before cooking up a bunch of handloads, randomly choosing bullets, to try some of the standard and hot factory loads with some of those bullets to see how they shoot in your .257.
A. You should find one that works and will get you hunting now, like Rem 117-gr RN or Hornady Custom Interlock.
B. You will probably find another that excites you and is much cheaper to handload and cook up an even better load (like the 115-gr Partition or the SST). I wouldn't use the SST at nearly 3,000 fps on close game, because I use the SST for downrange velocity, 250+ yards.
The .257 is very versatile cartridge. Most rifles shoot the 75-gr very well. My idea of a perfect .257 Roberts is a 6.5 lb with 21 to 22 inch barrel and iron sights or a light 4x scope, shooting a 117-gr SPT at 2750 fps.
