any 22 caliber center fire rifle/revolver will work 22 hornet,223 22-250,220swift,222 --but must be center fire
1.using a expended cartridge (or unprimed brass) drill out the base of the brass where the original primer went ( i use a 1/4" drill bit and then use a hone in my drimel to do the final fitting) and fit a 204 shotshell primer (black powder primer 204)
2get some 22 caliber pellets --I like the gamo raptors for squirrel and small game--
3 the pellet should fit the cartridge case and the 204 primer goes--- well you should be able to figure it out
i don't know what velocity I'm getting but at 30 yards it shot thru a piece of 1/6 pt and it's quiet enough so that my next door neighbor doesn't hear it from less than 100 ft
now back to savages
I tried shooting the 222 like coyote talked about but everything still fit afterward so I guess I just am lucky
