Took my Ruger 22/45 and this up in the hills today for some plinking. So glad I went with this can, there's no first round crack and it didn't change the POI at all . Sounds like a pellet rifle being fired. Still waiting on a new scope from Elknut before I can take out the .17 HMR . And I guess I'm either going to have to get my target barrel threaded on my 10/22 or buy an aftermarket one.
