I wonder what the explanation would be to why a rifle would do this? Mine shoots rather tight with different ammunition. It never sends shots an inch or better out of the groups at 50 yards. I do know they are not the top of the line .22 rifle. I never expected it to be, I just wanted it to be fairly consistent, which it is easily.I bought a BMR last spring, then sent it back to the factory within 2 weeks because of various issues. They fixed everything except for 1 or 2 out of 10 shots would jump out an inch or better at 50 yards which made it worthless for any competition. I tested it with at least 10 different ammos and finally sold it to a neighbor for half the price I bought it for. He gave it to his teenage son who loves it and has darn near wiped out the local tree rat population with it.
My guess is it had something to do with the stock. Possible flexing up and touching the barrel. I could have dropped it into a Boyds or filled it with fiberglass I suppose. The next step would have been adding in a barrel pad or stiffening the stock with epoxy. As luck would have it the neighbor approached me looking for a recommendation for an inexpensive .22. I sent him home with the Bergarra, an inexpensive scope, and a sling. His son could not have been any happier if it had been an Anschutz in a gold plated caseI wonder what the explanation would be to why a rifle would do this?
