is it possible to closley calculate muzzle velocity using a given bullet weight bc and such using the difference in elevation on the target at varying ranges?
if so could someone help me out?
the rifle is a browning xbolt 300 wsm 23 inch barrel
the ammunition is federal fusion 150 grain not sure of the ballistic coefficient. the advertised velocity is 3250
i sighted 2 inches high at 100 yards when shooting a group at 200 yards i was hitting 1.5 inches low that is a change in point of impact of 3.5 inches from 100 yards to 200 yards.
what kind of estimated velocity am i looking at here?
