What is to high of a number for a Ruger mklll to have been shot through it. Will that hurt the rifling in the barrel. I saw one for sale with almost 6000 rounds fired. What about the effects on the rest of the gun?
6,000 rounds, It's just been broken in
Mine is close to that and still in LNIB condition. Well, maybe not quite that good but little wear on the internals that I can see or that affect the performance of the gun. The only thing to check that might wear at that point is to see if the bolt locks open upon firing the last round from the magazine. It is an easy fix, but that is what wore on mine. Once I learned to slingshot it, that wear was eliminated.
Assuming it is made out of decent steel (as the MkIIIs are) a .22LR won't burn out the barrel in your lifetime. Overly aggressive cleaning would damage the barrel more than 6,000 rounds.
In summary, 6K for a quality .22LR pistol is nothing.
