My elevation is about 700' above sea level. 3,800' is pretty high! I guess that is why your FPS is fast too.
Also, have you shot much 180gr projectiles from a 1:10 in 308Win? Everything I read says its not worth it and 168gr is the heaviest/optimum bullet for a 308. But I wonder if the folks that say that are using 1:12 or 1:14 twist?
