It seems so little trouble to help shooter with this issue, but scope makers often just don't seem to care....
How to dial turrets — and not end up one full revolution too high or too low on the elevation:
Method 1 Buy a scope that has turret revolution indicators. The scope spec tables in the post below list which of 150 scopes DO have those indicators.

Method 2 Buy a scope where the turrets dial a lot of elevation, not just dinky 5 or 6 mils (15 moas) — but 10 mils per revolution. Then it is much less likely that you dial a full turn for a shot.
Method 3 Attach something to your scope, anything, whatever, that has two or three positions that can be changed by simply sliding some lever, clicking something — I still have to find something that works for me.
Whenever you turn the turret for more then one revolution, slide/click your little device to indicate the turret revolution you're one....
Method 4 with UTG scopes with lockable turrets Some UTG scopes have a lockable turret — they have a ring around the base of the turret that tightens the turret.
I usually don't use that locking ring, so it's set to completely loose.
The ring has a knurls, and on the first knurl I put 1 dot of whiteout, on the second 2 dots of whiteout, on the third 3 dots.
An the 15moa turret, when I dial a full revolution, say 20moa, I also turn the locking ring from 1 dot to two dots, meaning that I'm in the 2nd revolution of my turret.
[EDIT, thanks Centercut:]
Method 5 with a Scope with a Zero Stop ➔ What Centercut said!



: Some scopes have a zero stop. Some scopes can be modded with a DIY zero stop putting a suitable plastic of metal washer into the turret (ask on the forums for
your scope, or check YouTube).
This allows you to reliable return the scope to zero whenever in doubt on what revolution you are on....

I'd be interested to hear what others have to say!
