I have 2 guns I would like to recrown. One is a Rem 788 in 30 -30 and the other is a S&W mod 18 in 22 cal.The Rem has pitting at the muzzle but no other visible damage. The S&W has a very light burr on one of the lands. The accuracy is disappointing on both guns.
One person said to use a 9mm fmj bullet in a drill with lapping compound, and run it against the muzzle until it cleans up. Others say get a crown cutting tool with a pilot and T handle from a gunsmith supply, which would run about $100 and do it that way. Which way is best? I have heard of guns shooting poorly and when all other corrective measures failed, a recrown improved accuracy, even when the muzzle looked fine beforehand.
