HUH? how did that work? if it had a sleeve in the cylinder, how did you change to different shells? seems much easier to make two different cylinders.Ya I know......I thought it was a little odd in it. It had a steel sleev guide that fit in the cylinder so the 22lr did wiggle around much. If its different cylinder now that is a big improvement....w lr the one I was messin w id rather chunk rocks at a target.
