I thought I had my scope zero’d in (Hammers 3-9) finally on my Gamo Silent Cat. Using H&N super heavys to get FPS down. Got the shooting rests in and filled and was hitting the targets in okay groupings (compared to what was happening before) and I moved back to get a better range since I won’t be that close for the hunting I want to do. I moved back to around 50 feet and it’s on point for side to side but up and down it ranges like 2 feet. I have no idea why. I don’t know if my shooting style is just terrible or if I’m pulling it? I got it rested on the front bag and I’m using my hand under the stock to raise up and down and barely pushing it into my shoulder. It kicks so hard too so it may be throwing it off but gripping harder was what everyone told me not to do.
