Does anyone know of a reloadable cartridge close in caliber to .22? I know there is nothing factory and it would have a be a wildcat of some kind, which I am very unfamiliar. PA has a dumb rule that you may not use any caliber larger than .23 to hunt small game and I would like to reload for my small game hunting (why, just because). I would not be pushing the bullet very fast as it would be for edible game so I don't need a large case. At this point, the best I can come up with is downloading the .223 but that is a lot of powder or empty space in the case. Either way I would like something smaller...any ideas? Thanks!
