Hello group. This is my first post and you may have answered this elsewhere. If so, let me know. I am new to air rifles. I shot competitively with a .22 in the distant past. I bought a refurbished Browning Leverage .22 and it came with a 3x9 scope that made it difficult to load the pellets, in the beginning, so I used a 4x scope I had. As I got used to the Browning, I put the 3x9 back on and zeroed it in as best I could. I got able to put 10 shots through the size of a dime from 20 yards in my backyard, but it was off from the bulls eye by about half inch. So I corrected it and all of a sudden the shot group is way off. Now ten shots covered by a silver dollar with occasional flyers. I checked the mounting and the mount was tight. What happened. I like the rifle very much when it was dialed in, but this is unacceptable.
