I would like to use my .22 rifle but city law does not allow it. I have tried both springers and gas from .177, .22, and .25. My problem with gas is that the trajectory is not repeatable from shot to shot. The .22 spring breaker seems to work the best.
.22 shorts are subsonic. They will not set off shot spotters. And they’re quieter than my Gamo .177 single break action.
