Winchester Ammunition has introduced a new M-22 Subsonic .22 LR round designed specifically to function in semi-automatic firearms, while remaining subsonic from both pistol and rifle length barrels. The new M-22 Subsonic features a 45-gr. black-plated lead round nose bullet that has the equivalent energy of full velocity 36-gr. rimfire products.

In addition, the M-22 Subsonic utilizes non-corrosive priming and clean burning powder for reduced muzzle flash. The M-22 Subsonic was also created with suppressed firearms in mind, but performs just as well in unsuppressed rifles and handguns. During Winchester testing, M-22 Subsonic rounds measured 129 dB from an unsuppressed rifle. That is significantly quieter than a full velocity .22 LR fired from a suppressed rifle, which typically measures around 138 db. With the addition of a suppressor, M-22 Subsonic achieves a remarkably quiet 116 db.

"Suppressed firearms are growing in popularity. This is the perfect round for shooters looking to reduce the noise of each shot even more," said Brett Flaugher, Winchester Ammunition vice president of marketing, sales and strategy.

M-22 Subsonic will be available in 100-round plastic packs and 800-round bulk packs. For more, visit Winchester.com.
