Some of these were made and sold for the museum trade. They are used to whack sparrow sized birds off of branches w/o destroying their value as study skin specimens. They work a WHOLE lot better than rifled barrels.

Inserts are also made for .20 gauge and probably other gauges of shotguns. They are the size and length of a shotsell cartridge and bored to chamber a .22 shotshell off centered so that it can be fired with the normal firing pin.
