Re: 22 rimfire smooth bore
Often called and labeled by Remington as Routledge Bore on their pump 22's to be used in a parlor game of Mo-Skeet. I had the Rem 121 Routledge pump and it got the best distance and pattern with the still currently offered Winchester crimped #12 shot. I found the CCI shot shells kept too much of the shot in the blue capsule giving a limited pattern and shot count. The Winchester and I believe Federal still offers a crimped shell, both shoot open like a shotgun shell. Even with these like stated earlier the killing distance would be about 20 feet. Probably most often used as pigeon control inside a building so as not to put stray holes in the roof. I've used the Winchesters out of a revolver to be a snake killer. The effective kill range for snakes was no more than 5 feet.
