Gunsmithing .243 AI on a SA or LA

Re: .243 AI on a SA or LA

all my 243AI's have been on short actions. I never ran 115's but several ran 105's. they fed fine from a short action and I had plenty of room to seat them out.
 
Re: .243 AI on a SA or LA

If you want to get the most powder behind the 115's, the LA will serve yo well. You could also run a single shot SA. I have 2 built on shorts and really have to seat the 115's deep to run in a mag. I'm gonna start running the 107's a little faster and make better use of mag length.
