I know that the .22 caliber rimfire cartridge has been around along time and people have had occurences of having numerous afternoons of shooting up alot of ammo between 2-3 shooters, and the gun staying in the family for several generations, for example. Or the fellow who target shoots for precision and goes to the range alot.
I had read of a fellow in the American Rifleman magazine who had a bolt action .22 rimfire that had been used by several generations in his family and as he put it "it does not group as well now as it did when I had it as a kid in the 1950's", paraphrased as I cannot remember the exact words.
Has anyone worn out a .22 caliber barrel, or know of a friend/family member who did?
Also, I used to clean my .22 rimfire guns after each outing, had read that this was not really necessary as the bullet leaves a waxy lubricant in the bore. I now rarely clean the bore on them, just the action, bolt face, etc. Should I clean it like I do my centerfires, or leave it alone? My bores seem just fine when I check them with the bore light after not cleaning them for 2-3 years.
Thanks.
