[QUOTE="emp1953, post: 1781799, member: 71817"] Here are the easy things: THEY don't cost you anything to check, except time 1) Is it new(er) brass or old brass -> neck tension becomes suspect -> do you crimp the case neck -> does the bolt close easily on all your rounds 2) Are you loading the magazine or are you firing single shot mode -> next shooting session try shooting single shot mode, do not load the magazine -> bullets can jump forward due to recoil in the more powerful cartridges -> changes in case volume due to this will cause variations in velocity changing POI -> next shooting session bring a dial micrometer with you. -> shoot your magazine except for the last shot -> pull that round and measure it compared to rounds still in your cartridge case. 3) COHUNT touched on something, MIRAGE -> according to John Krieger of Krieger barrels (this guy knows barrels) -> the larger capacity cases can heat up barrels after 3 shots. -> In your cold temperature conditions, mirage from the barrel heat can occur at lower barrel temperatures along the entire sight line -> a scope magnifies the mirage effect and you end up chasing a moving target without knowing it. -> Allow more time between shots, even if it is relatively cold out. 4) How new/old is the barrel? How many rounds through it? -> Some barrels take 80 to 100 rounds to break in. Harder things will come in later posts I'm sure, like firing pin problems, spring etc. They take a trip to a gunsmith to check out. [/QUOTE]
