Description
Save money on the do-it-all combination that’s been written up in
several of the ”accuracy” publications: J-B and Kroil! Run a couple
of patches soaked in Kroil through the bore to get under and
loosen barrel fouling, then wipe away most of the crud with a dry
patch. Follow with J-B Compound to dig deep and remove the most
stubborn moly residue, powder, and copper jacket fouling. A final
pass with Kroil coats the bore with a rust preventive film.
