Fburtgx: I just got back from the Hornady site and they show a muzzle velocity for their 750 grain A-MAX bullet from a 50 BMG cartridge as 2,815 F.P.S. - that bullet had a muzzle energy by the way of 13,196 foot/pounds (ouch!)!!!
Then I checked their trajectory chart and that bullet at that speed when sighted in dead on at 200 yards dropped 35 inches out at 500 yards (or 1,500 feet).
I can't even imagine how much drop a 50 BMG projectile would have out at 11,319 feet (or 3,773 yards!)!
Debunking your "4 second" flight time though, the Hornady projectile would HAVE TO MAINTAIN that muzzle velocity from the muzzle then maintain that exact speed all the way out to 2.14 miles or 11,319 feet to get to that distance in 4.0209 seconds!
We both know that bullet can NOT do that speed for 2.14 miles to attain your guesstimate of 4.0209 seconds!
(I figured that out myself with some simple division 11,319' divided by 2,815' per second - resulting in 4.0209 seconds)
Hold into the wind
