Once again the "duh" hat goes on me. Yes the caliber I was referring to (in my head again it looks like) was .308. And the rifle I am shooting it in is a Rem 700 with bull barrell. I do also want to load for my M1A also but I am finding out that what works well in a bolt does not necessarily work in a semi. (Thanks RC 20). Is there a rule of thumb on loading for a bolt vs. semi (ie: decrease 2% start or something like that?) Or is it trial and error- little emphasis on error.
There is much to learn yet and you guys are a big big help....again Thanks.
