Used the PBA pellets and it's as loud or louder than a .22 rifle (no chit!) I put it away for awhile after I fired it on my residential backyard. Didn't want the neighbors reporting gunshots you know
the lead pellets are nice and quiet. I guess the PBA's break the sound barrier. Holy chit!
After dialing in the scope I was hitting bottle caps taped to a cardboard box at 25 yards consistently. Good times
