Re: .257 roberts +p loads
Yes, you can use the +P brass in your 257 just the same as standard brass. Actually, I'm not even sure the brass is any different than standard 257 cases. Had a M70 Featherweight in 257 some years back, and don't recall if I ever saw any difference between the 257 and the 257+P cases. I'm sure someone else can chime in here?
