WMR is a whole nother animal, All others are safe to interchange but may not all cycle. most new .22s are made for .22LR, .22 long is pretty much phased out. .22 shorts are safe to shoot in any .22 firearm except magnum but you will not cycle in semi autos and may not agree with some bolt action repeaters depending on if they are fed by box or tube magazine. I don't know of any box rifle or pistol mags that will reliably feed .22 short. Tube feed bolt actions should feed both.
