Whoever said the lubricant coating on .22 rimfire bullets ruined a gun is OUTRIGHT LYING! It's physically impossible for that to happen. .22 short/long/long rifle bullets are outside lubricated-same as any cast bullet you will see today. So shoot all you want and don't worry other than doing normal cleaning. It's a combination of bullet lube and powder residue that gum up the actions of .22s that are not cleaned regularly (especially semiautos) BUT will NOT ruin them.

So ive been reading up on how some 22LR manufactures coat the bullets with wax. Also read this wax can clog up your rifling.
I saw also a youtube video with someone claiming the wax from a 22 Thunderbolt round ruined his Ruger Mark III Pistol
Anyone had any experience with this? Lots of guys I know are shooting Federal and CCI loads from their pistols and are having pretty good luck.
