needs more ammo
The only issue I would have with 22 mag is noise. There are options to quiet down 22 LR with ammo choice or a suppressor. With 22 mag, is the extra range and power enough to justify the inability to go quiet? For either, it would be easy to store a single firearm and a pile of ammo in a compact package. If you expect the potential for dangerous animals or people, making less noise may be very important.
If a shooter already owns a .22 WMR rifle, that shooter can turn the noise down a notch with sub-sonic .22 WMR ammo. Having the extra punch of .22 WMR while being able to dial down the power to .22LR in the same gun could be pretty useful. Same idea of that .357 magnum rifle mentioned upthread with .38 special loaded in it.
