The first question is do you want to get into that cartridge? .22WMR (Winchester Magnum Rimfire) costs much more than .22LR ammo, costs more than reloading centerfire .22 cartridges, but costs less than buying centerfire ammo new. It has a little more range than .22LR but much less than any of the centerfire .22s.
If you're definitely not interested in reloading and you have a use for a rifle with a little more range than .22LR it's a good idea. Otherwise not.
