For no good reason beyond my own amusement I’ve input the same parameters into several different calculators just to see the difference in the solutions.

Basic parameters
245g LRHT or .433 g7 and 1.775”
2716 fps mv
8 twist
2.81” sight height
Zero angle, zero wind
Spin drift on
3000’ DA 70*
Coriolis off

First row is 2000 yd,
second row is 1000yd

Applied ballistic (w curve)
22.9U .7L 3.448TOF
7.2U .3L 1.348

Shooter ballistics
22.9U .5L 3.450TOF
7.2U .2L 1.347

GeoBallistics
22.7U .44L 3.433TOF
7.18U .15L 1.345

Hornady (tried 4DOF but the bullet isn’t in there so it kicked me to BC Calc and i can’t figure out how to enter bullet length)
22.01U .71L 3.36844
7.08U .23L 1.33487


Trasol
23.36U .55L 3.472TOF
7.24U .19L 1.351

Kinda wish I still had FFS nomad.

Surprised how close $10 shooter ballistic is with just the single g7 bc to $30 AB with an extra $10 custom curve… (would love for someone to explain that custom curve to me)
And $0 geoballistics is only .2 different at 2000yd.
Hornady and trasol are off .7 in different directions. Maybe Berger bullets aren’t high on 4dof priority list. Love the detail in their range table but it takes forever
