    A while back we found an lovely JC Higgins Model 20 twelve-gauge at Pintos for the ridiculous price of $100, and Linda put it on layaway as my Christmas present. We were picking it up last saturday and I spotted a S&W I-Frame revolver in .32 Long in the case. It was awfully rough, but I had a look anyway. However rough the cosmetics it was mechanically fine, and the price? $125. Shut up and take my money! I wound up with a second, unintended Christmas present.

    After a thorough cleaning I discovered that the bore was a bit rough but within limits... except for the last inch at the muzzle. I'll shoot it as-is, but if it's key-holing shots I'll cut away the bad section and remount the sight.

    Yesterday afternoon I decided to refinish the gun. I detail-stripped it, cleaning a century of gunk out of the mechanism in the process. After some careful polishing, sanding and reblueing I reassembled the gun. The already nice trigger is now excellent, and the gun looks great! No one would mistake it for a new gun, but that was never the point... preservation and cosmetics was the goal. Here's a pic of the results:

    So for $125 and a bit of TLC I have an excellent little historic shooter. Great Christmas present!

    Nice looking shooter! I hope you don't have to chop the barrel! I would love to stumble on to something like that myself!

    Good Morning Sir from Arizona...I have commented to you all so often about my lack of
    knowledge when dealing with guns....You wrote:

    Recently I was watching a crime solving program called FORENSIC FILES...the criminal had
    committed a gun crime and attempted to solve the bullet-proofing source by damaging the
    barrel of the offending gun with a drill type device in the end of the barrel...was the barrel of
    your new gun damaged in some same-sort of way...the forensic specialist put a hot wax in
    the bore end and was able to match up the lands and groves on the damaged bullet? Your term, "key-holing shots" Please 'splain? Thanks...Chief

    Key holing simply means going in side ways instead of front end first.

    When a gun isn't cleaned the bore can rust, and when this is serious enough you get pits in the metal. Small pits aren't much of a problem, as long as the bullet can seal and engage the rifling properly. But the bore near the muzzle of this gun is bitted badly enough that the bullet might disengage from the rifling, which causes it to smear across the rifling. This leaves lead deposits and can destabilized the bullet, resulting in poor accuracy or even 'key-holing.'

    Key-holing means that the bullet is yawing or even tumbling and hits the target sideways. This leaves an oval or rectangular hole instead of a round one. Bullets that do this are terribly inaccurate.

    If this happens there are two ways to fix it: reline the barrel (expensive and problematic) or cut away the bad section of barrel and re-crown the muzzle. This only works if the barrel is bad near the muzzle.

    Thank You Michael...that was an explanation as worthy as any I have ever personally done
    explaining to students how to disarm a MRK 1V MOD 2 device in a broken aircraft! That
    key-holing effect you explained...I've heard many military range butt-pullers call back to
    the shooter that there was a "tumble" with his weapon ...to have the gunners-mate check
    the condition at the armory... is "Maggie's Drawers" a term common for complete target
    misses or just on the navy/marine ranges? Chief

    Thanks Carver...Michael 'splained that term ...when a round tumble that way, can you hear it
    cutting the air differently than a straight-in round sound? Chief

    This will make a detectable difference in the sound of the bullet, but I do not know if a human ear would detect it; I have never been able to myself.
