A 3-DOF point-mass solver over the published G1 and G7 standard drag curves — the same method JBM Ballistics ran for fifteen years — with a 179-bullet library of manufacturer-published BCs. Pick a bullet or type your own numbers.
Read this before you rely on any number here. Predictions use the standard G1/G7 drag models and the data you enter — they are estimates, not measurements, and they are never load advice. Confirm with live fire at distance. For anything you load yourself, work only from current published manuals (Hodgdon, Sierra, Hornady, Lyman), start low, and work up. TruingLog publishes no load recipes and suggests no charge weights.
