- Excessive-Velocity .22LR (e.g., Federal, Remington): These rounds typically make the most of bullets that may attain larger muzzle velocities. They’ll additionally use hole level or extra specialised bullet shapes. The mix might result in a barely larger BC than CCI Customary Velocity, relying on the bullet design. Whereas velocity is normally quicker, a decrease BC than sure goal rounds nonetheless leads to a extra curved trajectory at prolonged ranges.
- Match/Goal .22LR (e.g., Eley, Lapua): Designed for excessive accuracy, these rounds prioritize high-quality parts and sometimes characteristic extra aerodynamic bullet designs. Anticipate a extra streamlined bullet design, with specialised profiles, contributing to the next BC worth, albeit with usually the same velocity to CCI Customary Velocity. They’ll present higher long-range efficiency and diminished wind drift.
The variations grow to be most evident at longer ranges. A high-velocity spherical may exhibit a flatter trajectory in comparison with CCI Customary Velocity, however the spherical’s decrease BC will nonetheless imply elevated drop previous sure distances. Match-grade ammunition will preserve a comparatively flat trajectory and present much less wind affect than each normal and excessive velocity ammunition.
The trade-offs are clear. CCI Customary Velocity trades some long-range efficiency for different benefits. The marginally slower muzzle velocity (in comparison with high-velocity rounds) typically contributes to a diminished report (the sound of the shot), much less felt recoil, and decrease value. It’s an ideal spherical for basic plinking, goal apply at shorter distances, and small recreation searching the place vary is not excessive.
Taking Motion: Sensible Software for Shooters
Understanding BC is simply half the battle; realizing methods to make the most of this data interprets into success on the vary. For these taking pictures CCI Customary Velocity, a number of issues come to the forefront:
