Quick answer

At 100 yards, a 1/4 MOA click moves the point of impact 0.262 inches and a 0.1 mil click moves it 0.36 inches. Both scale in direct proportion to distance, so at 500 yards those same clicks move 1.31 inches and 1.8 inches. This chart covers all seven click values sold, at 16 distances from 25 to 1,200 yards.

A click value is the amount of angle one detent of a turret moves the point of impact, expressed in a fraction of a minute of angle or a fraction of a milliradian. It is fixed by the erector mechanism and printed on the turret cap, and it does not change with tube diameter, magnification or objective size. What it moves in actual inches changes constantly, because that depends on distance, and that is the one number a shooter needs at the bench and rarely has memorized past 100 yards.

This is the single most useful table to keep in a range bag: every stocked click value, at every distance a shooter is likely to be working, computed once so it never has to be worked out under time pressure.

These figures are exact arithmetic from the MOA and mil definitions and the click values manufacturers actually sell, not a claim about any particular turret's mechanical repeatability.

What does one click move at every distance?

The working

Inches per click = click value x unit constant x (yards / 100). The MOA constant is 1.047197 and the mil constant is 3.6, both exact.

Turrets only move in whole clicks, so the number you can actually dial is the nearest whole click, not the exact fractional figure this table shows.

Every click value stocked on a scope in this catalog, read straight across for the distance you are dialling at. This is the core table on this page and the one worth bookmarking.

A 1/4 MOA click moves 0.262 inches at 100 yards and 1.31 inches at 500 yards, while a 0.1 mil click moves 0.36 inches at 100 yards and 1.8 inches at 500 yards.

Every figure is exact arithmetic from the click value times the unit constant times distance. No scope's mechanical repeatability is assumed; this is what the turret is engineered to move, not a measurement of a specific unit.

How many clicks correct one inch, at any distance?

Run the table the other direction: how many clicks of each value it takes to move the point of impact one inch, at the distances shooters actually zero and confirm at.

At 100 yards, correcting 1 inch takes 3.82 clicks of 1/4 MOA or 2.78 clicks of 0.1 mil, and both figures fall in direct proportion to distance.

Round to the nearest whole click, since a turret cannot dial a fraction. The remainder left on target after rounding is the residual error, usually a small fraction of an inch and rarely worth chasing further.

Which click value should you actually buy?

A quarter MOA click is the most common hunting and general purpose turret in North America, fine enough for essentially any shot a hunting rifle takes and familiar to the widest pool of shooters and ballistic apps. A tenth mil click is the standard on competition and long range scopes, favored for the same reason mil wins the broader unit argument: the constants scale in clean multiples of 3.6 rather than 1.047, which is easier to compute under time pressure at a stage or a cold bore shot.

An eighth MOA click, at 0.131 inches at 100 yards, is the finest common factory adjustment and shows up on target and benchrest turrets built for shooters who want to split hairs at the bench and are not in a hurry to get there. A full 1 MOA or half MOA click belongs on red dots and simple optics, where the reticle itself is far coarser than the adjustment and a fine click would be wasted precision. A MOA turret long range scope and a mil turret precision scope both dial correctly at any of these distances; the click value that matters is the one that matches your reticle and your ballistic data, not the one that sounds more precise on paper.

Frequently asked questions

What does a 1/4 MOA click move at 100 yards?

0.262 inches. A quarter MOA is a quarter of 1.047197 inches, the exact subtension of one minute of angle at 100 yards. This is the most common click value on North American hunting and general purpose scopes, fine enough for essentially any shot a hunting rifle is likely to take.

What does a 0.1 mil click move at 100 yards?

0.36 inches, exactly a tenth of the 3.6 inches a full mil subtends at 100 yards. This is the standard click value on competition and long range scopes, chosen because the round 3.6 inch constant is easier to scale mentally under time pressure than the MOA figure of 1.047 inches.

How many clicks does it take to move 1 inch at 100 yards?

3.82 clicks with a quarter MOA turret, or 2.78 clicks with a tenth mil turret. Turrets only move in whole clicks, so round to the nearest whole number and accept the small remainder left on target rather than trying to split a click, which is not mechanically possible.

Is an eighth MOA click or a twentieth mil click finer?

An eighth MOA click moves 0.131 inches at 100 yards, finer than the more common tenth mil click at 0.36 inches. A twentieth mil click, at 0.05 mil, moves 0.18 inches and is finer than a quarter MOA but coarser than an eighth MOA. Fine click values like these are mostly found on target and benchrest turrets.

Does click value change with tube diameter?

No. Click value is set by the internal erector mechanism and printed on the turret regardless of whether the tube is 1 inch, 30mm or 34mm. A larger tube gives the erector more room to travel, which increases total elevation adjustment available, not the value of a single click.

Why do red dots and simple optics use 1 MOA clicks?

Because the reticle itself, usually a single dot rather than a fine crosshair, is already far coarser than a fraction of an MOA would justify. A full 1 MOA or half MOA click is quick to count in the field and matches the practical precision the sight is built for, without adding adjustment fineness the reticle cannot actually use.

Researched, not professional advice. This page is compiled from published manufacturer specifications, published optical and ballistic formulas, and owner-review consensus, not hands-on testing. Figures described as a rule of thumb are shooter convention rather than sourced numbers, and they are labelled that way wherever they appear. Ballistic figures come from a point mass model using the ballistic coefficient the maker publishes, so treat them as a starting point and confirm them on paper at a measured distance. Confirm your firearm is unloaded with the action open before you mount, level, torque or bore sight anything. Verify a zero only on a supervised range or a safe, legal backstop, know what lies beyond your target, and follow the law where you hunt and shoot, including rules on land access and permitted cartridges.
