I have tried this off hand and off of a bag. It hits high with Super X, Aguila super sonic, Minimags, CCI Standard Velocity, Blazer 22, Remington Golden Bullet, and Federal GameShok. I thought that maybe it was the higher velocity ammo, but have seen the same results with slower stuff. The further downrange I set the target, the higher the POI. Has anyone experienced this? Any suggestions?
