How often does a .22 rifle/pistol need to have the bore cleaned to really perform well?
I know some people that never clean them. I am ashamed to admit that when in High School I shot NRA smallbore matches with a 52D winchester match rifle and never once cleaned it. Finally it dawned on me I should and it did not seem to make any difference. It always shot great. On the other hand, I notice that if I shoot CCI stingers out of my sig trailside when its freshly cleaned they shoot fine, after a hundred or so rounds of other ammo then going back to them, accuracy is terrible. So functioning aside, how often should rimfire bores be cleaned to keep best accuracy?
