Thread: Drop chart

Morning all. Wonder if someone with more ballistic knowledge than me could give me an idea of what the bullet drop would be with my 308. Ive chrongraphed the Sako gamehead thru My Bergara Extreme 18inch barrel at an average of 2680 fps.
Im sighting in 2 inches high at 100. Ive looked at ballistic calculators but im not sure im doing it right.
The bullet has a BC of G1/0.304 at 2680 fps.
I also chronographed Sako Gamehead Pro which interestingly group pretty much the same place as the gamehead soft point but was 200 FPS slower. I suppose thats because Gamhead Pro has a better bullet ballistically.
Any info appreciated.
