DOPE — Ballistic Data & Range Calculator turns your rifle or pistol data into a precise firing solution, right at the bench or in the field.
Build a loadout from your firearm, optic, and ammunition, then get everything you need for the shot:
• Firing solution — elevation and windage in MOA or MRAD, plus exact turret clicks
• True-scale reticle view — see your holdover on your actual reticle and target
• Range card out to 1000 yards
• Environmental corrections — temperature, pressure, altitude, humidity, and density altitude
• Zeroing aid — tap your shot group on the target and get the clicks to zero, with a guided troubleshooter when you're way off
• Rifle and pistol support, including red dots and iron sights
• Works offline — the calculator runs on-device
DOPE Pro unlocks unlimited loadouts, the full firing solution, the range card, environmental corrections, and the zeroing aid. Free includes the sight-picture view and one loadout.
DOPE gives estimates from a ballistic model and your data — always confirm your zero with live fire, and follow all firearm-safety rules and laws.
