Clean-22 Hyper Velocity uses a purple-coated 31-grain lead bullet with a round-nose profile, at a muzzle velocity of 1550 fps, for a speedy combination fully capable of taking headshots at squirrels in the top of the tallest trees. Now, a light bullet in the .22 Long Rifle at a higher velocity is not exactly a new concept at CCI; the Stinger uses an elongated case and a 32-grain bullet at a muzzle velocity of 1640 fps and has long been a favorite of both shooters and hunters.
