10/22 loses zero with each mag change
Anybody already have this problem?
I have a basic 10/22. Then changed the stock to Fajen, the barrel to Magnum Research graphite/carbon barrel.
Added the Ruger scope base, and a Simmons 22 Mag 3x9 AO scope. Now every time I change the magazine the zero changes! At 50 yards, it will jump 2 inches to the right, or inch 1/2 toward the 2:00 o'clock, or 8:00 o'clock positions. Every mag change. If I shoot through the magazine, it seems to group like one inch, but it's suddenly a nice group in a seemingly random spot.
The scope mounts, rings, base, all are tight. I've never taken apart the internals, only changed the barrel. The barrel WAS tight, all sorts of warnings are given not to over-torque the barrel screws. Doesn't seem like a loose barrel would only change when I take out the magazine and refill and re-insert it.
Just wondering if anybody had this before, what it was? Thanks for any help!
