I have done a fair amount of reloading, but just basic stuff. At any rate I haven't blown my self or any rifles up. I just bought a Ruger #1 International in 7x57 Mauser with 1: 8.75" rh twist. I have RCBS reloading equipment, I am looking at buying dies. I only have this rifle in that cal. and only plan to shoot at the range punching holes up 200 yards. All my other reloading dies are full length I was looking at dies at Epp's and I see Neck sizing dies. Is this what I should be using ??? I am thinking yes. What do you say. Also what bullet weight would work best ?
