I think I may have an expanded cylinder in my .22lr Heritage revolver but I find it hard to believe that a standard .22 lr round would have the power to do that. A long time ago one of my hot .357 loads expanded a cylinder in my S&W Model 19, and now I am experiencing the same stuck empties in one of the 6 cylinder slots. I have only fired maybe 5 rounds of standard Winchester ammo and maybe 30 rounds of CCI CB shorts. I wonder if maybe the shorts have gummed up the cylinder but the other 5 work fine. Before I send off the cylinder to Heritage I thought I would check in here for thoughts
