22 magnum ammo, also commonly called 22 Winchester Magnum Rimfire ammunition is a rimfire cartridge introduced by Winchester in 1959. Although the "R" in "WMR" stands for rifle, the round has been successfully chambered in both rifles as well as revolvers; in fact, although Winchester developed the round, other manufacturers had chambered revolvers for it before Winchester had produced a rifle in that chambering.

The 22 WMR is a dandy little varmint round, provided the ranges don't stray too far beyond the 100 yard mark. Initially, the bullets were in the 40 grain range; but today, ammunition is available in a wide range of bullet styles from 25 to 50 grain. 22 Win Mag as a caliber produces velocities ranging from about 800 fps in revolvers to upwards of 2,300 feet per second in longer rifle barrels. Since the round produces higher velocities than the .22 LR, it is more popular for small game, especially varmints, and might even be a bit overkill at relatively close ranges. Head to this article at our blog for more on how 22 WMR stacks up to 22 long rifle.

The wide range of factory-loaded 22 WMR ammunition gives the round quite a bit of versatility. The savvy hunter can stoke his gun with anything from the speedy 25 grain Hornady NTX to 40 grain offerings from CCI and Fiocchi to a 45 grain heavy hitter from Hornady and even a heavy 50 grain from Federal. And, even better, those weights come in a variety of bullet styles including full metal jacket bullets, hollow points, flex tips, and polymer tipped.

    I had purchased a Henry Lever action 22 magnum rifle, put a Nikon Prostaff 3-9×40mm scope on it. I had shot armscor 22lr ammo before and decided to break the Henry 22 magnum in with it. I did purchase the Armscor USA 22 magnum 40 grain ammunition, made in the USA, stay away from the Armscor made in the Philippines, coated with wax and it is messy in your hand and chamber. The break in of the Henry 22 magnum was great, the Henry put groups inside of a 1/4" at 50 yards shooting off of homemade sandbags. It shot so well it is my ammunition. Shoots as accurate as the CCI 40 grain 22 magnum ammo. Give it a try, your rifle/pistol will love the Armscor USA 22 magnum ammunition.

    I have been shooting with the Armscor .22 Magnums for three years, and I have had no problems with it. I recently shot them with my S&W 351C and was well pleased with the results. I will continue to buy Armscor from Ammot To Go, who is great to do business with.
