In this video you can see and hear the difference between firing a standard bulk pack high velocity .22 Long Rifle round, and a CCI .22 CB Long cartridge.
In a future post I'll compare various forms and brands of .22 rim fire ammunition for both velocity and accuracy in testing. For now, a few comments on a recent range session with the CB longs.
I recently repaired a .22 rifle, and found myself at the range doing function testing. I was also mounting a scope a scope on the .22 in preparation to eradicating a few thousand bunny wabbits that are eating our garden. The problem with the rifle involved a round jammed in the action. A .22 CB short round which lodged while chasing down a huge Australian fanged killer rabbit that was eating our broccoli. The rifle is rated for short, long, and long rifle but it seems the CB shorts are just too..... well....... short. For this session I picked up a box of CCI CB Long cartridges. Brigid mentioned these in a post, and it started me thinking. These rounds have the same ballistics as the CB Short, but arrive in a longer case to improve functioning. The price is the same as CB shorts, being slightly more than one arm and half a leg. ($8.95 a box around here).
After mounting the scope and dialing it in with bulk pack .22 LR rounds, I turned to the CB's for final tuning. These are the rounds that will be busting bunnies in the garden, and their low power requires excellent shot placement. In exchange for reduced power, there is a dramatic reduction in noise as the video demonstrates. Rated at 710 FPS with a 29 grain conical bullet, they have slightly more power than a decent adult air rifle.
How do they stack up in accuracy? Well enough to makes wabbits wobble in wonder as they wander away in wost hope. (Oh... ain't I a stinker?)
