Fundamentals of Ballistics for Precision
Earlier than diving into zeroing, it is important to know some elementary ballistic ideas. These rules underpin why a 25-yard zero is a sensible and efficient place to begin.
Muzzle Velocity (MV)
That is the velocity at which the bullet leaves the barrel of the rifle. It’s a key think about figuring out the bullet’s trajectory and its eventual influence level. The MV of a 7.62×39 spherical usually falls inside a particular vary, depending on the load and barrel size, influencing how shortly the bullet drops over distance.
