New to this? Start by measuring your group
- Fire a group (3–5 shots is plenty) aiming at the same point of aim each time.
- Find the middle of the group — not any single shot, but roughly the centre of where they clustered.
- Measure straight up or down from your point of aim to that middle, in inches, mm or cm. That's the number that goes in “how far your group is off centre” below.
- Fill in the calculator with that measurement, your range, and your scope's click type — it does the rest and tells you which way to turn the turret.
Enter your numbers
Not sure which is yours? It's printed on the turret cap — e.g. “0.1 MRAD” or “1/8 MOA”.Dial this much
Which way? Dial elevation up if your group is low, down if it's high, by the amount shown.
How this works, in plain terms
A scope's turret is marked either in MOA (“minutes of angle”) or Mil (“milliradians”) — both are units of angle, not distance. The further away the target, the more actual inches one unit covers: roughly 1 inch per MOA at 100 yards (about 5 inches at 500 yards), or roughly 3.6 inches per Mil at 100 yards (about 18 inches at 500 yards).
So to work out how many clicks you need, this calculator converts the distance your group is off centre into MOA or Mil (using your range), then divides that by your scope's click size. Most club scopes use ¼ MOA clicks, but some use ⅛ MOA, ½ MOA, or Mil-based clicks — pick the one that matches your scope from the list, or choose “Other / custom” and enter it yourself. Your scope's exact click size is usually printed on the turret cap or in the manual, since it can vary between models even within the same brand.
Worked example: at 100 yards, if your group is 4 inches low, that's about 3.8 MOA. On a ¼ MOA scope, that's 15 clicks up. On a ½ MOA scope, that's 8 clicks up. On a Mil scope with 0.1 Mil clicks, that's about 11 clicks up.
This is a reference tool for elevation, not a substitute for confirming your zero on the range. Always re-check with live fire before a match, and if in doubt, ask one of our coaches.
Zeroed at one range and shooting at a much longer one, and want a predicted starting point rather than a correction? Try the elevation calculator instead.
