"Click" consistancy

[WithoutWarning]

For any of you out there that can give some insight
to this inquiry, regarding the precision of turret 'click'
values.
I'm reading "The Ultimate Sniper" at the moment and have
just finished the section that stress's the importance of
having 'good glass' on your rig. Plaster mentions the difference
between geared, or positive drive turrets as opposed to
friction operated ones.
All higher end scopes have a positive drive like; Leupold Mark IV,
Nightforce, S & B, US optics. . ., and I have these on my two rifles.
(Not all four, only one per rifle..)
So, the question I have is; if one is to constantly adjust your POA
up and down say, 1 - 15 MOA, I can't help but wonder why the
affected area within the turret doesn't wear ? How does it hold onto
an exact 1/4" @ 100 'click' value ? (Or whatever value it is).
I've prooven to myself that the friction turrets DO wear out.
This may not be the most accurate question, but I'm sure those of
you 'in the know' can gather what I'm asking.
Thx.

I have never worn a good scope out I take my NightForce up 47 to 49 MOA and ever where and it does return to Zero when I stop it there..

you get what you pay for,but you only got to pay once

Well - All you have to do is put the click mechanism (such as a ball/detente arrgt) on the driven side of the gearing - no worries about wear induced backlash. Alternatively, just use precision gearing, made of some wear resistant material.

Eventually they will all wear out, it is a machine after all. But odds are good it will out last you in all respects. - dan

I have found it informative to look at Warner Tool (google with the word sights) ... the owner often uses the web name "2 good screws"...for obvious reasons. The precision of his sights are unquestioned in certain circles - they ought to be at $500 US a pop...which folks happily pay for his quality. Anyway even with the very best equipment and materials ... there will be some wear ... this is also true of scopes. Overtime everything will wear. And you can also bet that the windage and adjustment screws in your Leupold are not "hand lapped" like Mr Warners are before assembly.
