Hello all,
I am a strict Highpower and prone slowfire bolt-gun competitor. Recently I have switched from my AR to an M1A purely for the challenge. The M1A has a GI barrel but I can still shoot into the 750's with it. My problem is this. I was using WIN 308 cases because I had so many. that cases gets alot of abuse from the M1A and i do not use them more than 1 or 2 times. I have a large amount of Lake City match brass i'm goign to start using but i'm also planning to rebarrel soon with a Kreiger match SS barrel with a simlar chamber as my bolt gun,168 to mag length seated to the lands) my questions are:
1. if i go ahead and prep all that brass with a Redding full length, s bushing, small base die, it should be good to work in the new barrel or my exisiting or should i go ahead and rebarrel before next season and prevent sizing confusion? it's easy to size for a GI barrel, not so much matching a LC LR case to a new match chamber.
2. is standard Lake City that much different than the match? minus the primer crimp, and what it was fired in. 7.62 lake city is fairly common, but I dont want to buy a lot fired from a machine gun that is not going to be sized.
Any help to this lengthy post would be great. I don't have many local resources to help me out and the M1A is a lot different than my AR.
Thanks.
