[QUOTE="edge, post: 200909, member: 5030"] On a ROUGH basis: Assuming 265 grains @ 3100 fps at Sea Level and a BC of 0.770 2500 = BC = 0.829 5000 = BC = 0.8938 7500 = BC = 0.9632 10000 = BC = 1.038 This assumes that the pressure, temperature and everything else is the same! This is HIGHLY unlikely! That is the reason the you need to shoot for yourself under known conditions. edge. [/QUOTE]
