.22 WMR
.22 WMR, or .22 Magnum, is the big brother of the .22 long rifle round. While being a great small game ammunition in its own right, the .22 WMR is also a respectable self-defense round. Many shooters may not realize it, but a .22 Magnum actually produces more muzzle energy than both the .380 ACP and the .38 Special rounds. Powerful, low-recoiling and relatively inexpensive, the .22 WMR has many applications that make it a great choice.
