My brother keeps buying what I call laser guided cannons and has me reload for him. Supposedly he gets 1 hole groups from one of my handloads out of a 257 wm at 200 yds . He just bought a 6.5 300 and wants me to get the competition dies bit I cant seem to find them and wondering if I even need to. Read somewhere that the freebore likes the grip a standard bushing gives. I'm thinking I might have got lucky with the 257, just standard rcbs dies. Would definitely appreciate any and all feedback, thanks!
