The Need For Speed – The New Winchester M-22 Subsonic

Winchester Ammunition is one of a few ammo companies still turning out innovations in the realm of rimfire ammunition.

Think the groundbreaking 17 Winchester Super Magnum, introduced just two years ago, that shattered the speed record with a deadly accurate 3,000 fps muzzle velocity. Centerfire performance at rimfire cost is what the 17 Win Super Mag brought to the table. Winchester continues breaking ground in the rimfire world in 2016 with the introduction of a subsonic .22-caliber LR round.

The Need For Speed – The New Winchester M-22 Subsonic

The M-22 Subsonic is designed specifically to function in semi-automatic firearms while remaining subsonic from both pistol and rifle length barrels. The new round features a 45-grain black-plated lead, round nose bullet that has the equivalent energy of a full velocity 36-grain rimfire product. In addition, the M-22 Subsonic utilizes non-corrosive priming and clean burning powder for reduced muzzle flash and easier care and cleaning of your firearm.

M-22 Subsonic is ideal for the increasingly popular suppressed firearms, eliminating the audible crack of faster rounds, even when fired through a suppressor, for the ultimate in low-noise shooting. The ammunition works equally well in unsuppressed fire­arms, too, reducing the sound of shots even without a suppressor

So how much more quiet is M-22 Subsonic compared to standard long rifle loads? In Winchester testing, M-22 Subsonic measured at 129 dB from an unsup­pressed rifle, which is significantly quieter than a full velocity .22 LR fired from a suppressed rifle (138 dB). With the addition of a suppressor, M-22 Subsonic achieves a remarkably quiet 116 dB.

M-22 Subsonic Features: 

  • Subsonic velocity from both rifles and pistols
  • Sure functioning of semi-automatic firearms
  • Low noise levels in both suppressed and unsuppressed firearms
  • 45-grain bullet weight
  • Available in an 800-round bulk pack and 100-round plastic bulk pack
