Could'nt quite get the best info on different websites regarding bullet drop between the two. I sighted in my muzzy and shoot 3.5" high at a 100, 1.5" low at 150 and 6.5" low at 200. What do you guys think the difference would be shooting at 12000 plus altitude? I read barometric pressure is all that counts, not sure if thats true. If it is here's my data. Where I'm at is sea level barometric pressure is 29.63 shooting Thor 250 gr. bullet and 100 gr. of BH 209 powder. Where I'm going barometric is ~ 30.39. What do you guys think? Should I compensate?
