Ballistics & DOPE
A ballistics calculator that lives with your load data.
Build a true DOPE card — G1/G7 drag, muzzle velocity, ballistic coefficient, sight height and zero — then save it against the exact rifle and load you shoot. No re-typing numbers into a one-off web form every range trip.
Free account includes match scoring & results. The ballistics calculator is part of ShotGroup Pro.
The real thing — a full range card, computed from your load and conditions.
Why it's different
Most calculators forget everything the moment you close the tab.
ShotGroup's does the same math — then remembers the rifle, the load, and the conditions, so your DOPE is ready the next time you shoot.
Real drag models
G1 and G7 ballistic coefficients, muzzle velocity, bullet weight, sight height and zero range — the inputs that actually change your come-ups.
Saved to your rifle & load
Build a profile once — 6.5 Creedmoor in the precision rifle, 9mm in the carry gun — and your DOPE is there next range trip. No re-typing.
Prefilled from your reloads
Keep your load recipes in ShotGroup and the calculator prefills your bullet weight straight from the recipe you actually run — no re-typing grain weights.
One account for your scores and your dope.
ShotGroup is the only shooting app where the scoreboard and the training are the same account. Start free with match scoring — add Pro when you want the ballistics calculator, drills, and the classifier predictor.
