There are so many things that cold cause this. Start by checking your scope mounts and rings. Change to another proven scope. Clean the copper out of the barrel, etc. On your loads, do you crimp. Have the cases been trimmed to the proper length. Are you dropping powder and not weighing each charge. That's a start. Back to the still. Spelling, I don't need no stinkin spelling The older I get, the better I was. | |||

The general rule is check 1st-scope, 2nd-barrel and 3rd-bedding. | |||

My Ruger MK II Stainless drove me nuts for years with inconsistent groups, had it pillar and glass bedded, re-crowned, trigger job, etc. nothing helped. My usual routine was to shoot 6-8 three round groups and the loads that showed promise I would load in 5 round groups and on the next range trip they would not shoot consistently. One time I noticed that the groups always got bigger after I cleaned the gun, even with the same loads. I ran an experiment with not cleaning the barrel between range visits and after about 20-25 rounds it settled in to a solid 3/4"-1" rifle. Right now I have a little over 320 rounds through it since it was last cleaned and it still shoots 3/4"-1" groups.

Confirm what the others have said. Should you be confident that it's not you, then see a good gunsmith about that bedding. Cheers and best of luck | |||

Clean barrels can present accuracy problems . DON'T EVER clean a 22 target rifle !!! It took me over a hindered rounds to settle mine back down ( an at the time I wasn't smart enough to know what was happening ) So I fed it MATCH AMMO ELY TenX !. Boy talk about STUPID I kept shooting and CLEANING !!! I almost got a rubber stamp and tattooed my forehead once I realized what I had done wrong !!!!!!!!!!!!!!!!!!! When I go target shooting or hunting ; A ; I check all action screws scope mounts B ; I sight my Rifle in shoot my groups of which ever loads I plan on using . C; I DON'T CLEAN until after I'm done hunting or target shooting and I'm not going to shoot that particular Rifle maybe for a couple of months . I Never clean my 22's Barrels any more period only chamber and bolts .   | |||
