Sorry you are having trouble. But my question is if you were getting nice, satisfying groups with roundballs, why did you try something new at all? I just counted it up and I' ve had my Remington 700 ML for 6 years now and I' ve shot it a total of 9 times. The first shot out of the box was a dead on bullseye at 50 yards. I shot it the second time to make sure it wasnt a fluke. I put it away after that and the only shots I' ve taken with it since have been one practice shot each season to make sure the sights are still on, or to take a deer. I dont believe in messing with a good thing...
Good luck to you.
