Free G7 Ballistic Solver — Calibrated to Your Rifle
An online ballistic calculator that solves against your real rifle and your confirmed load — not a textbook bullet. Range, wind, Coriolis, and spin drift, tracked cleanly from supersonic through transonic into subsonic. Free, no paywall, and it runs right in your browser — no install required.
Solve against your rifle, not a generic curve
Most calculators start from the advertised BC and a manual’s muzzle velocity. Apex starts from your confirmed numbers — the per-rifle BC, the chronographed muzzle velocity, and the zero environment you actually shot. The solve is G7-canonical with a G1 fallback when a bullet only has G1 data, and it stays honest as the bullet slows down so your dial doesn’t quit on you when the bullet does.
- G7 canonical drag, G1 fallback when needed
- Per-rifle BC, muzzle velocity, and zero environment
- Wind, Coriolis, and spin drift
- Live atmospherics — temp, pressure, humidity, density altitude
A ballistic app with cloud backup
Lose your phone, lose your dope — that’s the recurring complaint with app-only solvers that keep everything on the device. Apex syncs every rifle, load, and session across web and Android, so your confirmed solutions survive a dead battery or a new phone. No Google account required, and your data stays yours.
Trued data lives in one place
A solver and a logbook aren’t two tools — they’re one loop. Every trued impact you record sharpens the next solution, and a confirmed load you trust beats a perfect prediction you can’t. And if you developed that load with tracked load-development data in the first place, you’re not truing from scratch — you’re confirming numbers you already trust.
