Specially Made for Accuracy in All 22 LR Firearms - Standard Velocity 40 gr Bullet at 1070 ft/sec Traditional Match Ammunition for 22LR is generally traveling at "Standard Velocity" of about 1070 ft/sec... As fast as it can go without going super-sonic (its subsonic). This avoids the buffeting that can detract from accuracy as the bullet passes through the sound barrier. This sub-sonic velocity is complimented by an extra consistent manufacturing process that gives CCI Green Tag far better accuracy than off-the-shelf 22LR ammo. Subsonic 22 Ammo is preferred by many small game hunters. The slower velocity is believed to put more "Whack" on small game. It's also preferred by accuracy lovers because it doesn't lose any stability as it slows down (High velocity 22 ammo is known to flutter as it passes through the sound barrier).
