this is just as fraught with issues as estimating velocity from drops.... have a play with a calculator and see what difference in drop a .1 difference in G1 BC makes - it pales in comparison to the uncertainty and noise in all your measurements.

fair enough, to be honest I've never had enough discrepancies in calculated drop vs actual drop to worry about it out to 600yards

@grandpamac I'll check tonight. @Seventy Six: with the bc 0.435 and velocity of 3050?

@Micky Duck: scope hight higher. bushnell 3-12x50. would think it is closer to 2 inch. Won't make that much of difference though

Will depend on your rings on my rifle a 50mm scope is still 1.6inch
