I recently acquired a Hopkins & Allen 922 .22LR rifle. Very good condition for its age, but not surprisingly the barrel is almost devoid of rifling, whether that is from being leaded up or corrosive ammo, I'm not sure yet. The rifle flings bullets all over with no regard to where you're pointing it.
What's your favorite method for scrubbing a .22 barrel of lead? And if the rifling is indeed beyond hope, who is reputable for relining a .22?
Thanks, Heath
