My blog on the Ruger Lightweight Carry Revolver (LCR) chambered for .22 Long Rifle has brought up a groundswell of requests for the gun to be chambered in .22 Winchester Magnum Rimfire (WMR), better known as .22 Mag. It looks to be especially attractive with the introduction of new loads, such as Hornady’s Critical Defense with a .45-grain FTX bullet, which according to factory data leaves a short 1 7/8-inch barrel at 1,000 fps, delivering a muzzle energy of 100 ft.-lbs. So why can’t you buy a .22 WMR LCR right now? The .22 Long Rifle seems to work fine, why not the .22 WMR?
