"CB Long" is low power and low noise 22LR ammunition. We call it "Yard Ammo" because it is no louder nor powerful than many air rifles that you can shoot in your back yard. The CB Long bullet is only 29 grs in weight and the "Long" case positions it close to the rifling for best accuracy. Clean burning CCI propellant and priming... Velocity is subsonic and just about 710 fps (like many airguns - see ballistics/specs). We tested CB Long ammo in a 24 inch 22LR Model 97D Rifle for an afternoon and it worked perfectly. Plinking beverage cans as far out as 30 yards, we found CB Longs to shoot accurately and quietly, punching holes and knocking the can around. We suggest cleaning with a boresnake (below) every 50 rounds or so. And, semi-autos may not cycle with such low power. Otherwise, CB Long loads and fires like any other 22LR ammo and is lots of fun! 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).
