*Notes: These ballistics are for factory loads, not handloads (unless noted otherwise).
Barrel length affects velocity at various rates depending on the load, and almost all velocities are measured out of a 22 inch barrel. As a rule, add 50 fps per extra inch of barrel if your barrel is longer than 22 inches; and subtract 50 fps per lacking inch of barrel if your barrel is shorter than 22 inches. This does not apply to the rimfire cartridges. |
