[QUOTE="Mikecr, post: 357332, member: 1521"] Michael, I believe you're muddling up TOF -vs- LAG within it. The 168smk may have arrived earlier, but it lagged more. That is, there was a larger differential between it's potential vac arrival(w/resp to MV), and it's actual arrival. There would be less lag with the big AMAX regardless of MV, because it's velocity drops off slower than the 168. And with drop, it's just the rate of gravity over a bullet's TOF. Air density plays no role in it, other than to change that TOF, by influencing BC, which causes LAG, and allows increasing drift at the same time. BC works equally well for both drift and drop, all by itself. Otherwise, we would have to invoke two BCs. One for drop, and one for drift. [/QUOTE]
