I recently picked up a project rifle, and I will need to clean up the chamber a bit (rifle is a .30-30). The chamber has some rust and pitting, and you can only seat the cartridge around 2/3 of the way in. I'm hoping a standard .30-30 reamer will clean up the rust and return the gun to working condition, but may end up requiring a .30-30AI. Anyone have a lead on where I could pick one up? Thanks!
