I've used it in a Ruger 10/22 TD and MKIV Competition and had good luck. Maybe I'm one of the lucky ones or my guns are looser than some. I've also got some HUSH 22lr that I haven't tried yet. Maybe this weekend.
I have Sonic Flip 100 (miniRIC) and actually like them. I've had them about 2 years now. I got them from Hearing Life over by Bass Pro in Tulsa. Batteries (size 13) last about 10 days wearing them 15 hrs/day. I also got the TV box so I could watch television again. I'd stopped watching...
