Original release notes
Seven new languages, more free rifles, and ballistic coefficients that carry their drag model everywhere. YOUR OWN RIFLE, FREE Build a rifle of your own and keep one a friend shares with you — on top of the three starter rifles the app comes with. SEVEN NEW LANGUAGES Greek, Finnish, Galician, Hebrew, Hungarian, Icelandic and Kazakh, fully translated throughout the app. COEFFICIENTS THAT KNOW THEIR DRAG MODEL Every ballistic coefficient now travels with the model it was measured against — G1 or G7 — through saved loads, the BC ladder, every tool and the solver itself. Loads you already saved are tagged automatically. VERIFIED CATALOG UPDATES Bullet and reticle data now arrives cryptographically signed, so every update you install is authentic. ALSO NEW Custom drag curves join Ballistics Pro, alongside accuracy refinements across the calculator, the reticle simulator and the atmosphere model.
