[QUOTE="farmboykjb5.9, post: 1504397, member: 23580"] Hi all, just wondering if anybody would know what would cause a new gun to shoot 1/2”-5/8” group then ten minuets later load the same handload and shoot again and it jumps out to 1.5”- 1.75 group? I have 3 different guns that are doing this which includes Rock River predator hp 308, My own built 6.5 Grendel (not cheap built either), And a Ruger M77 Hawkeye predator in 6.5 creedmore which is making me the maddest cause my brother has the same exact gun and his shoots any handload good and mine is temperamental. Scope mounts are torqued to spec, rings are lapped and torqued to spec, there’s no stock to barrel contact. A box of factory were used in each gun for break in before starting to handload. Any help would be greatly appreciated, thanks [/QUOTE]
