LETTER OF THE MONTH
CCI Velocitor
Q The guy at my local gun shop talked me into buying a brick of CCI .22 Velocitor rimfire ammo. He claims it is the fastest and hardest hitting rimfire ammo on the market. Is this true?

A CCI Velocitor has a published muzzle velocity of 1435fps for a 40gn hollow-point bullet, and it has 1095fps remaining at 100yd. Resulting energy figures are 183ft-lb at the muzzle and 107ft-lb at 100yd, so I guess it could be described as being the most powerful .22 LR cartridge available.
I shot four five-shot groups with my Lithgow LA 101 topped with a Swarovski 6x36 A-series scope at 50 and 100 yards off the bench. The results at 50yd were groups of .75, .86, .90 and .70; at 100 yd groups measured 1.60, 1.40, 1.75 and 1.70 inch.
This is all the more remarkable for two reasons. First, there was a slight breeze blowing, and second, because high-velocity Long Rifle bullets travel in the trans-sonic velocity range. This is the worst area for accuracy – breaking the sound barrier at the muzzle and passing through it again on the way to the 100yd target. Radial dispersion from the centre was only .95” on the poorest group of 1.75”. For this reason, all match ammunition is subsonic to reduce wind drift.
