Your rifle, your load,
one card.

Bullet path, turret dial, wind, velocity and energy at every range you care about — and at the top, how far you can hold dead on and still stay in the vitals.

What’s included

Built for a dark stand

Amber on near-black, oversized figures, and nothing to swipe through.

Point-blank range — for your rifle, your load, and the vital zone you choose — worked out from the zero your rifle actually has.
Bullet path and turret dial on one card — out to 1500 yards.
247 factory loads across 46 cartridges — carrying the manufacturers’ own published velocities and ballistic coefficients — or type the numbers off the box.
MOA or MRAD per rifle — at your turret’s click value.
Wind, velocity and energy — at every range on the card.
Rows past 800 yards marked as reference — not proven dope.
Solved entirely on your phone — no account, no sign-in, and nothing leaves the device.
Optional local conditions lookup — off by default — with it off you get standard-atmosphere numbers, exactly like a printed drop chart.

Honest about the physics: DeadOn solves a point-mass trajectory against the standard G1 and G7 drag models — the same physics behind every mainstream ballistic calculator at hunting distances. It does not model Coriolis, spin drift or aerodynamic jump; inside 500 yards those move a bullet a fraction of an inch, far less than the error in an advertised muzzle velocity. Past about 800 yards that stops being true, and the app says so on the card. Chronograph your load and confirm your zero on paper — no calculator replaces that.
