Ran across an odd gun today on the Henry website: Henry Garden Gun .22 LR smoothbore.
This is a specialized gun for the little .22 shotshells, aka “rat shot,” that can be fired occasionally from almost any .22LR rifle or pistol. As they point out in the blurb, firing shot through a rifled barrel will eventually erode the rifling though. The Garden Gun is essentially the same as the well-known Henry lever-action .22, but without the rifling. I think it could also fire normal .22 ammunition but accuracy, and possibly muzzle velocity, would be terrible. Like all Henry guns, it is a little on the pricey side ($436 MSRP). It’s interesting though and I’m sure there is someone somewhere who would have real use for it.
