[QUOTE="Deputy819, post: 1507320, member: 98025"] Morning Gentleman! Having an issue with my .338-06 and need some ideas on where to start "trouble-shooting" so as to avoid just groping around in the dark. It's a Savage 110 (originally .30-06) that I rebarreled to a .338-06 and had the factory stock both pillar and glass bedded (Devcon). It's a hunting rifle and it consistently shot 1-1/4" groups at 200 yards, but recoil and muzzle rise was substantial. So, instead of putting a muzzle brake on it (like I probably should have) I had my Smith put it in a much heavier Bell & Carlson stock with pillars and Devcon glass bedding. I also figured "what the heck" and had the barreled action cerakoted and the whole thing turned out great. One problem though.....Now it wont turn out anything better than 2-3" groups at 200 yards. None of my previous PROVEN hand-loads work (SD/ES below 10) and I'm at a loss. I've tinkered with seating depth and powder charge with no success. Action screw torque is at 65" lbs front and rear, both barrel and tang are free-floated and all scope base and ring screws are torqued to proper factory recommended specs. Would cerakoting and changing stocks affect a rifle in such a dramatic way? Let's hear it.... [/QUOTE]
