JB for smoothing actions?

That certainly can happen, especially in those older Standard Models like I had in 1960. I actually ruined the chamber on that one dry firing it. The newer Mark II's and III's do have a firing pin stop that keeps it from striking the edge of the chamber mouth. I understand that repeatedly dry firing thousands of times can bend and deform that firing pin stop enough in some cases to allow contact with firing pin and the chamber mouth. I do dry fire my Mark III Hunter some but do keep a close eye out for any deformation of that firing pin stop that might allow damage. BTW, Ruger says it's OK to dry fire.
