I've got a Buckmark, and several kinds of 22 shotshells, but they will never meet! As accurate as my gun is, I'm not going to take a chance on gumming up the barrel with that snakeshot. I don't think it would do any permanent damage, but why do it if they won't even cycle the action. If I need to perforate a snake, I'll take the ten hollowpoints in the gun over #12 shot anytime! Now if I have snake loads for a 44, that's a whole different story!
