RE: The Perfect Zero-Point blank range?
Thats where I always zero my rifles in, my 308's are zeroed for 325 yards......
Point blank range is explained pretty simple as if a rifle was to be perfectly flat and shot, the bullet trajectory inclines(rises) slightly out of the muzzel and the point blank range is where the projectile crosses the line of the muzzel....
Weapon________approx 162 yd out 7 "high__________________325ys projectile passes line of sight of muzzle_____________falls into dirt...
