Details
This product is one of CCI's top performing rounds. It is loaded to match your shooting skills with the maximum amount of knock-down power available for a 22 LR. It is a cousin to the renowned "Stinger" ammunition but with a slightly heavier bullet designed for improved long-range ballistics performance.
E
ach frangible lead hollow-point bullet is gilded (coated) with a thin copper plating to reduce muzzle build-up and to help the bullet retain its shape during feeding (into the chamber), flight, and to some degree, impact.
The frangible, segmented design of this bullet creates three distinct wound channels upon impact to take varmints out quickly, while also allowing for safer shooting in environments where ricochet is a concern.
This round has a muzzle velocity of 1050 fps, keeping it well below the sound barrier, for
quieter shooting. This makes the round a particularly good option for those utilizing a suppressed firearm.
