Again, I want to thank you for your help. I have been speaking to Air Venturi and they are helping me with this issue. It's funny that I have a Gamo swarm magnum that shoots a 7.56 pellet at 1150 fps and I can group a quarter size at 50 yards?
I have a. 177 Venturi Avenge-X and I can't get any decent groups at 50 yards. I have tried pellets weights from 7.56, 8.4 to 10. At 10 yards, I can get a 10 shot the size of aspirin. This is my first PCP rifle. Help!
