Used to load for my buddies 257 "Bob" and he liked one load that involved IMR-4895 and 100 gr. Sierras. I'd have to dig out the 3 ring binder for the details. He shot up a bunch of factory ammo and gave me the brass. Had lots of +P cases and regular cases. Just kept them segregated and didn't think much of it because we weren't running any real hot loads. Now I wish I had weighed some cases to get an idea (?) of the difference between +P and non +P cases. He sold the gun a few years ago but now I'm gonna start loading 257 again. He just told me he picked up a Mod, 700 Classic in 257 Roberts from 1980-something when they chambered a different cartridge annually in the classic. Was 1982 the year they featured the Roberts?. I found the cartridge to respond well to handloading and from what I've seen of it I like it. Even though I prefer my .25-06, but that's just me. P.S. I think the Roberts is the only rifle round I can recall where they get into +P rated stuff.
