Smyth Busters: Cleaning .22 Rimfire Barrels

With their unbeatable combination of wisdom, experience, and charm, Brownells Gun Techs Steve Ostrem and Caleb Savant debunk some myths about cleaning .22 LR barrels. One myth is that cleaning will ruin a .22 barrel and it'll never shoot accurately again. Caleb thinks this myth is the result of people cleaning a barrel from the muzzle and damaging the muzzle crown, which CAN diminish accuracy. If it's done right, cleaning won't damage the bore, but..... Steve's message to the OCD contingent is lighten up - you don't have to clean the bore every time you go to the range, unless you shoot ammo with really dirty, gunky powder. But DO clean the action every time you shoot the rifle, especially on a semi-auto. That story you've heard about primer residue being overly abrasive? It's not.

What about shooting a lot of lead bullets? Won't that lead up the bore? The guys give us the straight skinny on lead fouling, too. But when you see your .22's groups opening up, then it's time to clean the bore!
