Shot Solver

I don’t know what I’m doing — walk me through 7 steps

Pick your cartridge, then your bullet — the two dropdowns below.
Measure sight height: bore center to scope center, with a caliper.
Zero at 100 yards on a calm day, and confirm it is really on.
Shoot five at 100, measure the group, and type it into Your group.
Check the scope really tracks what it says — see .
Chronograph if you can, and enter the average as muzzle velocity.
Go and shoot. Read the wind — that part is yours.

Steps 1 to 4 are enough inside 300 yards.

Muzzle-velocity SD — optional ft/s Leave it blank if you have not chronographed this load. With it, the card below separates the part of your dispersion that scales with distance from the part that grows faster.

Conditions —

Standard sea-level conditions are already assumed. Inside 500 yd, temperature and altitude move the solution by a fraction of your group — so fill them in if you know them, and leave them alone if you do not.
