I reload for a friend who has a Remington 30-06 in semi-auto. It has a 18" barrel and the current group size we have is about 1 1/2" @ 100 yds. I've never loaded for a semi-auto and can only assume that with a 18" barrel, 1 1/2" @ 100 yds. may be the best he can hope for, in terms of a hunting load. We're using IMR 4064 with a WLR primer, topped with 180 gr. Hornady BTSP. Do any of you have any comments in regards to this? Are we on the right tract, should we keep tweeking the load, etc.
