I can get my clicks to match up to around 1200m. But from there and to 1600m my Ballistic coefficient calculator is way off.
I guess it have something to do with the bullet flight speed getting to low and the bullet drops even more.. or?
Rifle: Sako TTG-42
1 twist in 12in
Ammo: Lapua .338 250grains (16.20g)
Muzzlevelocity: 888m/s (2913 FPS) at 26C (78.8F), 913Hpa (26.93InHg)
Scopehight: 5.6cm (2.2in)
One click is: 0.100 (MIL)
Zero range 100m (109.4 yards)
Im using Bulletflight.
At 1600m im using 200 klicks.
So.. Need help figuring out WHY the Bc7 only match to 1200m and HOW i can calculate/get an accurate number from 1200-1600m. (besides shooting dope test)
