I have used my 15-22 for loads of varmit control but I won't any more. My last shot (with my up till now very reliable Winchester Super X 40gr sub sonic HP, suppressor, 4x scope) missed the pigeon's head/neck/spine/vitals and tore out its chest. From my preferred hunting distance of around 10m. Some my DOPE and mechanical offset was spot on. Second pip down on the mildot scope right on its noggin. Should have been a clean decapitation like all the others. Ended up snapping its neck.

Maybe it was a freak occurence. Maybe my scope was off (it shot perfectly the nect weekend when checking zero) Maybe my barrel nut had loosened (it was tight when I replaced the hand guard recently) Maybe I just pulled my shot. But I have broken my BRNO out of the safe for this job from now on. Quieter too.
