I was wondering for some feedback on the 22 and shot shells. Lil things for the garden/pest control. I have no experience. But I remember reading several articles about smoothbore 22's that were popular at times past. I know speer makes shotshell 22 with the plastic caps to hold the load of tiny pellets, but federal evidently makes a crimped version also. What's the skinney on shooting these out of rifled barrels? Hurt the bore any? A buddy ask me to an indoor shoot, American Legion, & they use 22 rifles with the crimped federal shot loads at lil targets at 16 feet range. Indoor turkey shoot! Sounds like a hoot, but wondered if any damage to rifled bores & if anyone still mfg's. smoothbore 22's. Thanks.
