My 10 year old son is doing his science fair project on ballistics of the 308 caliber rifle comparing wind drift and trajectory of bullets of the same weight (almost) and approximate same velocity but having differing BC's.
Not going to be overly complex and firing will take place at 100, 200 and 300 yards.
Federal factory ammo will be used with the 168 gr match king and 165 grain Barnes. Federal data shows the initial velocity to be the same and with weights within 3 grains it should be good.
Firing results will be compared to the data as provided by Federal.
The best part of this is that the school is fine with it. Obviously no rifle or ammo will be there however there will be targets, photos and projectiles.
Hopefully the day we shoot has a fairly predictable and steady wind....
