Going thru some numbers on a theoretical rifle at 5000 yards using AB app
Specs
375 bullet / 400 gr CE lazer @ 3500 fps
Density altitude 0
Wind 0
337.4 MOA
11.8 sec flight time
Altitude at max arc 1400 ft
Standard rifle prone w/ bipod shoulder to bipod length 24"
0 moa rifle (theoretical)
.001" movement at either shoulder or bipod or combination of both during firing is 7.5" deviation at 5000 yards (1 hair is .003")
2 fps difference in load (3502 fps) 337.0 moa .4 moa off = 20.94"
5 fps difference in load (3505 fps) 336.4 moa 1.0 moa off = 52.35"
Combination of .001 shooter deviation and 5fps muzzle velocity 59.85" off
Now throw in a true 1/4 moa rifle and shooting mat that moves around - easily double that.
Then throw in some wind and wind reading from ground level to 1400 ft agl
There's always that pesky dispersion problem too
Sounds simple
