With a quality .22 the barrel/chamber life is probably longer then you will be alive relative to shooting it. Many are still doing well and accurate after 100,000 rounds. There are reports, like from Lija that even 200,000 rounds have been observed and still providing acceptable accuracy to the owners with the exception of bench rest shooters. Those folks win or lose by hundred's of an inch.
I don't have any references relative to documentation but back in the 80's the Lawrence Livermore National Laboratory did some testing on non-magnum .22 rimfire barrels and simply quit testing at 75,000 rounds. This was for non fully automatic weapons. With those you can burn up a barrel because of heat very quickly if you fire in a sustained mode.
The military said that was plenty for what they were interested in and told em to put the effort in what their original charter was.
Incorrect cleaning though is another story!
You can screw up a .22 barrel in a couple of those cleaning cycles especially if you clean from the crown (muzzle end) instead of the chamber.
I don't remember for sure if it was Dieter Anschutz or not but it was an Anschutz family guy that said "you will never wear out an Anschutz barrel by shooting it but you will by cleaning it....."
He was against rods and bore brushes.
The debate on clean, not to clean, how to clean, how not to clean, what to clean with, has been going on at least as long as I have been shooting which is over 50 years.
If 100 guys/gals respond to this thread relative to the above, IME, you will get 33% of em saying one way, another 33% saying another way and the final 33% saying a different way then the first 66%.
All of the responses will be anecdotal though so you will have to pick which ones "turns you on".
