The solver only knows what you told it. Ballistics App Troubleshooting
A ballistic solver is only as honest as its inputs. When your solution and your impacts disagree, the calculator is almost never wrong — something you typed is. This is the list we run to find the bad input, from the rifle profile down to a factory reset, before we lose faith in a tool that works.
- Pillar
- Rifle System
- Level
- Advanced
- Use when
- Solution ≠ impact
- Covers
- Inputs, atmos, menus
You dialed the solution, broke a clean shot, and the round landed somewhere the app didn't promise. Frustrating — and almost always self-inflicted. Solvers don't drift. They take muzzle velocity, a BC, atmospherics, wind, and an angle, and they do the same math every time. If the answer is wrong, one of those numbers is wrong.
Work it from the inside out: the rifle profile first, because a bad zero or muzzle velocity poisons every solution at every distance. Then the bullet and its BC. Then the conditions you fed it. Then the menus most people forget are even on.
A note on truing: don't true your BC or velocity to chase a single bad impact. True at a known distance, in good conditions, with a solid position — correcting your come-up to within about 1 MOA at that range. Trueing to a flyer just bakes the flyer into every future call.
The Checklist
Tick each line as you clear it. Nothing is saved — it's a live scratchpad for one pass down the list. Reset and run it again.

Rifle profile first — a bad zero corrupts everything downstream.
Trust the math, audit the inputs
When the solver and the steel disagree, the fastest path back to trust isn't a new app — it's a clean audit of what you typed. Nine times out of ten it's the zero, the muzzle velocity, or a sub-menu someone left on. Find it once and you stop second-guessing every solution after.
This is also the argument for hard DOPE. A solver is a tool; a card of confirmed come-ups you've shot and written down is the backstop that saves the day when a phone dies, a compass won't calibrate, or you just don't have time to chase a bad input on the clock.
A checklist is the map. The range is the reps.
Reading the steps is one thing. Running them under a shot timer with an instructor reading your process is where it sticks. Come put it to work.
