The load, and the figures its drawing is made from

IdentityWho makes it, and what it is for.

ProjectileThe figures the drawing and the solver start from.

Ballistics

Downrange, solved

Solved at the reference barrel of 127 mm from the G1 coefficient and the load's velocity retention. A different barrel gives a different curve.

At the muzzle

MuzzleThe solver’s figures at the reference barrel, where the curve starts.

Downrange

The same solution as the chart, at each distance the solver reports.
