[QUOTE="Shortmagman, post: 805071, member: 10723"] You can shoot your loads at various distances and measure the drop out to say 300-400 yards and from this and using the ballistic coefficient of the bullet and with a ballistic program you can estimate the velocity of your round. Example: Using the Sierra Bullet Infinity Program I came up with this. By the way this program includes the ballistic coefficient of each bullet. 190 SMK with a 100 yard Zero 2700 ft/sec velocity drops 14 inches at 300 yards, and 31 inches at 400 yards 2800 ft/sec down 12.8 at 300 and down 28 inches at 400 2900 ft/sec down 11.7 at 300 and down 26 inches at 400 This will become more accurate at longer distances so if you can shoot out to 600 yards or more it would be good.
