OK, so it's not 22 WMR, it's actually 22 Rem Jet Magnum. That is a little confusing for the novice. But I guess you get the economy of 22 LR, and then when you want to slit someone's ear drums next to you at the range or "ding" some jack rabbits, you load up the Jet's. Great, just what I need, another loud toy to reload for!!
