I have several .22LR rifles and handguns, but only one .22 WMR rifle, a CZ455 that, after some tweaking, shoots 1" groups at 100 yards with CCI and Rem. 30 grain V-Max type tips. I don't do much plinking with it, except for a few steel targets at 100 yards or so.
Yesterday, I shot another woodchuck with it at about 20 yards and it opened him up pretty well, more like a .223 at 100 yards. It's a light rifle that is my favorite walk-about rifle for varmints. It should take down Eastern Coyotes under 100 yards and woodchucks beyond that.
I can carry a hundred rounds in my pockets and not be inconvenienced, not that I shoot that many when walking around, but sometimes I take a couple different types, one of my best and some others to plink with that aren't as accurate as the good stuff.
