Franks post took what I had concluded on my own and added valuable input, thanks. I do believe that there is some benefit to be had from the bb practice. Repetitions build muscle memory so getting a correct firing grip, drawing and aligning the sights and squeezing off the shot are all good things to practice. I will just be doing it alot more deliberately for a while. The upside was I didn't manage to hurt my center fire shooting
either so I guess I caught myself in time.
