Try free float 1st! Most of my personal rifles I've worked on benefited from a free-float barrel. I have a Rem 788 .222 in particluar that when acquired shot good 1" groups (almost perfctly round for some reason). I got a new scope for it, it needed cleaning and the trigger was "gunky" for some reason(it was a bait-shop acquisition). What the ****. while it is apart, re-do the stock, glass bed it (using Dev-Con) and see what happens. The bore got JB'd, the stock got refinished and Dev-Con'ed, the action got cleaned well and when I re-zero-ed it with the new T/C 3/9 Hunter scope-.5" 5 shot group w/ 50gr Moly Nosler Ballistic Tip BT and Win 748 in whats his names Pet Loads favorite for .222Rem. BTW-My Bishop-stocked Mauser98, Rem 700 .25.06 ADL, Rem 700 HB Varmint .223, and Savage M10 .220 Swift are all free floated. Note to self-handloading works wonders!
