I had a couple of rifles do this. The culprit in my case was the scope. I have a Simmons scope that will not stay together. The first time it was almost new, so I blamed the rifle, jerked the scope off was about to put it on another rifle when I noticed that it rattled. Simmons repaired the scope for $20.00 handling. When it came back I put it on a different rifle, assuming it was good to go. I blew another couple of boxes trying to zero that rifle when I realized it had to be the scope again. It's still around here somewhere, waiting to go on a "gunshow special". Try a different scope if you have one.
