Thanks for the reply. I should clarify that it was my second shot on the second group of 3 that hit high left. I did think about the heat of the barrel as I was shooting and usually wait about the same time between shots but I had shot the first 5 shockwaves with no issues and the shots were spread evenly as far as the time it took to swab and reload as I did with the Powerbelts. That could still have something to do with it as you mentioned. I guess theres several things that could have attributed to the strays but i was just curious if the Powerbelts ability to rotate when pressed on the pellet, more than the Shockwave may have had anything to do with it. Thanks again.
