Interesting results that agree with the similar data reported at The Box O' Truth. Seems that rifled barrel shotguns are an item of somewhat narrow utility, good for launching slugs and not much else.

Useful for hunting deer in annoying jurisdictions where they won't let you use a rifle, and as a powerful "car stopper" / hard barrier penetrator at moderate range.

You should see the comedy of shooting 3" .410 in rifled ".45 Colt" pistol barrels of the gray area "no, really, it's just a .45 Colt with REALLY LONG" chambers. You can hit six police qual targets line abreast at 5-7 yards with a load of #7 shot instead of a slug.

Been there, done that, laugh at people that take perfectly usable .45 Colts and make them into worthless shotguns with shot and the MV/ME of a .410 slug is less than that of a standard .45 Colt loading. I got a bastardized .45 Contender barrel for FREE from somebody that had made it a worthless .410 and used it became a breech block and exctractor to stub a useful barrel in after shooting it a couple times, laughing, and throwing it in the corner for future donor parts purposes.

Amazing an entire subsection of the manufacturing industry supports that whacky idea and people buy them instead of .45 Colt snubbies/derringers.
