Resetting a scope to zero - How to avoid losing track of how many turns? Rev counters, limiters?

[gunsrfun1]

Today at the range I sighted in my .22 for 50 - 200 yards, using a starting point of "0" because that is the 25-yard zero elevation I set a few weeks ago.
At first I was counting rotations of the (elevation) turret and keeping track of numbers on the turret, but that got all messed up when I tried to return to 50-yard zero. It turned out I went too many turns over, but I couldn't readily figure out how many rotations too far I had gone.
Then the light went on and I started counting clicks, and of course writing them down. So I got everything back to normal after about 15 rounds of experimentation, and now I can shoot 25 - 200 yards POA/POI by adjusting elevation from the starting point of 25-yard zero, by counting clicks.
But I have to be very careful in keeping track of the clicks. For my old brain, that can get a bit challenging.
My question: Is there some method of identifying the proper "0" setting that you need to return to (i.e., how many turret rotations to turn), so that if you lose count of clicks, you don't go x number of rotations too far, or y number of rotations too few. So that even if you are counting clicks and you loose count, you know how to "find your way home" on the turret.
Since all "0" settings look the same, I would think there is not, and that you have to be diligent about counting clicks. But I thought I would ask.

PS - I'm told there is something called a rev counter or limiter that helps you figure out "where you are" on turret rotations and enables you to "dial back down" to zero (or whatever setting you want the turret to "hard stop" at). But from searching the web, it seems like these devices these have to come already installed on the scope, and are not aftermarket items you can add to a scope. Can someone clarify?
Thanks

Thats what turrets were made for. Its just an extended knob that marks the ranges.

You can use a fine tipped metallic colored marker.... I usually use a sharpie... And make a line at the base of the turret cap that correlates to your zero Rev.
If you're really inclined, you can make a line at every revolution. But I found that more confusing than necessary.

You had the same problem that I had. I started writing down stuff like that in a little notebook so I can remember what’s the starting point and points for other distances.

Then when I introduced a different type of ammo things really got screwed up. So, I still need to work on what the hell I am doing. Duh?

Say you get a used scope and don't know where it's set at. First send it to me and you'll get a handwritten thank you card. I keeeeeeed. Don't send it to me.

Starting with a turret, turn it down all the way (or up). Then count as your turn it all the other way. Now you know how many "clicks" (if such applies) you have for that turret. Now, divide by two and that's your zero for that turret Now, try the same with the other one. Ditto with results.

Next, mount it and boresight the rifle. Try it at 25 yards and fire five shots. Adjust the scope now and confirm the adjustments by firing five more shots. When you're around the x-ring, then move it out to 100 yards.

You're talking about a zero stop, and yes, it comes /is built into, the scope. Super handy to have, makes it so much easier. My match guns for long range have scopes with zero stops, zero the scope at 100 yards, set the zero stop. You can set it to stop at zero or go a few clicks below if you wish, my buddy Jeff does three clicks below for his .22 LR scope where we are zeroed at 50, but shoot under that sometimes. It still stops at the same place every time, just go back three clicks to zero. Me? I set my zero stop at zero and hold under if needed.

An example of a scope with a zero stop (You can get a zero stop scope cheaper than this one, but they have a nice video on it.)

Different scopes use different methods for their zero stop, but they all do the same thing.

I set the zero stop 4 clicks below zero on my Nightforce.

Thank you Walkalong. I get the feeling that these come mainly on higher end scopes (like Lightman's Nightforce).
My .22 is wearing a Burris Fullfield E1; wouldn't mind a zero stop if I could add one to it. Does anyone make any type of aftermarket zero-stop turret I could swap out? Or, is this something that has to be built in with the scope?
Thanks again.

Rev indicators are typically available on almost all scopes with turret style adjustment knobs - it’s the older “coin click” dials in sunken sockets which don’t offer any indication at all. And of course, some select few unfortunately designed turret models… Some scopes have very specific rev indicators, some are resettable, some are more “intrinsic.” Kahles scopes, for example, have a red button which pops up from the top of the turret cap when it has been turned past 1 full rev, indicating it’s a rev above its zero, and have a zero stop which prevents the scope from being turned below zero (or a desired offset below zero) so it can’t ever be a rev low.

Some other scopes just have indicator lines on the scope body beneath the turret, and the shooter has to remember which line corresponds to the zero position. For these, I just mark with appropriately colored paint pen or magic marker the line which corresponds to my zero.

But….

Your E1 doesn’t have any means of rev indication, as the capped knob doesn’t move with changing elevation. The only trick you can use is to zero, then pay attention to how many revs from bottom or top your zero is, so then you can twist it all the way to one end and dial back to your zero. Your E1 has 40moa of adjustment capacity and 17moa per rev (what a strange number!?!?) and with your 25moa rings, you should be less than 1 rev away from the top of the scope at a 100yrd zero (~12moa out of 17 per rev), or within 7 from the top at a 50yrd zero. Just be careful to sneak up on the ends gingerly. You could mark your turret where your elevation indicator meets the top of the scope with your current zero, to know you’d be getting close if you were on the same rev.

My Crimson Trace 5-25 does not have a zero stop, nor does the turret move up and down, you really have to pay attention.

That said, it's a nice scope, but I would not want to shoot competitions with it.

How interesting! I don't think I've noticed The scope turret's not moving up/down on any of my scopes.... Including the fullfield.
But then again, most of those style of scopes are on guns that are zeroed and then not messed with much if at all........
And now I'm going to pull all of my guns out of the safe when I get home and play with.... I mean inspect their scopes.....Oh darn.....

An example of a set that don’t pop up to re zero rather have three hex screws per turret that tighten to a stem, this also has a rev indicator on each turret.
When I start a scope at 25 yards, I must remember the correction x4
Example: if my impact is four inches high I adjust down < 16 minutes.
