    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?

    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.

    6000? That like only 20-50 times to the range. There are some that might think about cleaning it at that number. :D

    I have a Ruger Super Single Six that I fired 500 rounds a week though it for the first year I owned it. That was over 25 years ago and I still shoot this gun alot. Round count has to be well over 60,000 rds. Gun is still as accurate as the day I got it and still as much fun to shoot.

    Yes, this. Do check the bolt hold open. A lot of people like to use that as a bolt release - it's not. Never simply depress the switch and let the bolt slam home like you would with a 1911. The mechanism will wear out from this. While holding the bolt back then press and hold the lever and finally release the bolt.

    Or just do a 'slingshot mod'.

    I shot a MK II Ruger in bullseye leagues for close to 10 years. Between weekly practice, Leagues, weekend plinking, etc, LOTS of bricks of Ammo were sent down that Barrel. I would not worry about 6000 rounds. IF you COULD ever wear one out, Brownells sells upgraded barrel/upper receivers that require no gunsmithing to replace. Buy it and enjoy it.

    I have owned my first 22/45 MkII since 1995. While I now own more than several, when I was a humble public servant it used to be my only .22 self-loading pistol. I lost count at the 18K count about 10 years ago.

    I still shoot the snot out of it. I have no idea what is through it but it must be north of 30K. The pistol has been taken to the screws to be cleaned by a professional gunsmith twice but other than install a speed strip and buy ammo I have done nothing to the gun.

    Think about it like miles on a diesel engine vs miles on an open wheel Indy car engine :D

    I know i have personally put 6000 through my MKIII. Still works like new.

    6000 rounds is nothing. .22 lr rounds are easy on the barrel, with softer lead and lube. If something were to have a problem, it would probably be something on the slide from battering, but Ruger mk pistols are tuff.

    This....

    More 22's are ruined by cleaning rods than by the lead bullets that they shoot.

    A lead bullet can't burn out a bore, just make it better. As long as the foreign substance that is a cleaning rod, is not introduced.

    I would be more interested in how often he cleans it. That is a more accurate description of the wear of the barrel and action.

    Hundreds of thousands are high round counts for a Ruger MKIII. Anything less is still the break in period. :D

    I have an MKII...with well over 75,000 rounds through it, still shoots like a champ.

    A good 22LR handgun or rifle, the rifling in that barrel will last for many lifetimes. Like Cordex said, cleaning the barrel will do more damage than shooting. I have replaced a firing pin, and extractor in My 1982 MK 2, but that is all.
