Scope Click Values

[Alex Wheeler]

Level is not important. You want the yard stick inline with the turret travel. Start by lining it up with the vertical part of your reticle. Crank in 20 or more moa and see if the center of the reticle its still centered on the yard stick, or its edge which would be better. If not tweak the scope checker until you can run the turret up and down and it travels along the yard stick edge without horizontal drift.

What I mean is if you sent someone down range holding a yardstick from their belt to their neck, and the faced you and then leaned forward, you would get error induced into the measurement.

Nice thing with hanging a long yard stick is that you dont need a target backer and do not need to be at any sort of rifle range to check tracking. And with the Field & Cave scope checker, you dont even need a bench.

I can hang the yard stick from a tree in my back yard, set up the scope checker with 2 scopes on my tripod, place my tripod exactly how far away I want it at whatever measured distance and go to work. Piece of cake.

I wouldnt mind having that Target USA scope rest to put my scope checker on because with that thing on a bench, it would be more stable than my tripod for sure. Unfortunately, it's $325. For that money I might as well make my own. I have enough scrap lying around to cook one up. A picatinny rail, aluminum block, and old brake rotors for weight ought to do the trick

Understood, and your correct.

I understand that as well however the distance to the target coupled by the amount of ange skewing the measurement would add a factor to be determined. Now would a tester calculate that in Moa? I'm not smart enough for that nor could I shoot the difference.

Anyone ever hard mount their 1/4 MOA per click scope focused on a yardstick at 100 yards then measure reticle movement over 40 clicks?

Did it move exactly 10 MOA?

For the shooting I do, I don't care if it moved 10 MOA or 15 MOA, as long as the scope adjustments are repeatable throughout the ranges I shoot. Trying to equate angular measurements to length measurements is just another factor that needs not be present.

Well, easy to tell it's Winter time.

Its interesting that benchrest rules for multiple range group aggregates state MOA is inches per hundred yards. No conversation formulas to get the trig version.

I think it's irrelevant to the thread topic, "Scope Click Values". But is a typical response by you, to yet again attempt to smear benchrest, even by hijacking discussion (once again) in doing so.... lol

I've effectively checked the elevation turret tracking accuracy of my long range scopes several times using a 48" ruler hanging from a tripod set exactly 100 yards out. I lay my rifles on the front and rear rests and strap the rifle securely to the front rest to avoid rifle movement. I start at 10" from the bottom of the ruler then dial 36 MOA up. At that point the crosshair should be at 37.69". It has always come back to the 10" starting point after dialling the turret back down to zero, confirming the rifle did not move during the process. So far my three Nightforce SHV's have been right on the number and a Sightron SIII is within 3/16" of an inch or so after the 36 MOA turret excursion. This test obviously does not tell you if your scope holds POI from recoil but can provide some confidence (or indicate a malfunction) for those that don't have a scope checker.

Correction to my post. After running the turret up 36 MOA the crosshair should be aiming at 47.69" on the ruler equaling a 37.69 excursion since it started at the 10" mark.
