TrueDope: Ballistic Calculator

TrueDope is a ballistic calculator for long-range shooters and hunters. Set up your rifle and load, enter the conditions, and read your dope: elevation and wind holds in MIL or MOA, with clicks for your turret. It works with no signal.

YOUR DOPE
• Elevation, wind hold, drop, drift, velocity, energy and time of flight at the ranges you choose
• MIL values written to a tenth, the way you dial them; MOA and clicks for any turret
• G1 and G7 drag models, point-mass solver checked against the US Army BRL reference program (McCoy's MCTRAJ)

CONDITIONS
• Wind speed and clock direction, shot angle, temperature, station pressure and humidity
• Density altitude shown as you type; set pressure from altitude when you don't have a meter reading

RIFLES AND LOADS
• Profiles for each rifle and load: BC, muzzle velocity, zero, sight height, click value
• Built-in library of manufacturer-published BCs, each cited to the maker, or enter your own
• Imperial or metric

TRUEDOPE PRO: ONE PURCHASE, NO SUBSCRIPTION
• Truing: enter what you actually dialed at one or more ranges, and TrueDope trues your muzzle velocity or BC to match
• Range cards: a printable 4 × 6 in card with your dope, to tape to the stock
• Unlimited profiles (the free version has two)

YOURS, ON YOUR PHONE
• Works fully offline. No account, no sign-up
• Your profiles and every calculation stay on your phone

TrueDope uses a point-mass model: it does not model spin drift or Coriolis effect. Verify on actual targets; this is a prediction, not verified dope.
