So I know that I'm going to get an answer along the lines of "you have to check and see", which I know is really the best way to be sure, but because I'm lazy ;)



Are bushnell Elite/Tactical scopes turrets actually graduated in 1/4 moa clicks (TMOA), or are they 1/4" @ 100 (SMOA)?

For the sake of examples, let's say for a 10x40 or a 6-24x50

Obviously at closer ranges, and depending on your group sizes to begin, it may be a moot point.

MOA is an angular measure 1/60th of a degree that by magic at 100 yards 1moa egal 1.047 inches ...

so there will be a variation let s say at 50 yards or 200 yards ... now if you are shooting MOA in meters that is more challenging ...

if your scope is First plan or second plan there is another factor to add.

the bushnell 10x40 is the best to be confused ... turrets are in MOA while the reticle is in MIL ...

Yes. I know that. :) Also, I have one of the older 6-24x50 thats mil reticle, "moa" turrets. The newer ones seem to be mil/mil.



But the question is, what are the turrets actually graduated in.

if you look in the manual, it says 1 click = 1/4" @ 100 yards. But it also says that 1 moa = 1/4" @ 100 yards, which we know is not really true, it's rounded off.

So has anyone actually verified whether Bushnell's turrets are "True" MOA (~.262"/click@ 100y), or if they are "shooters" MOA (.250"/click @ 100y)?

the only answer you can get will be trying to get one from bushnell lab ...

that will hard to measure in situ.

That was what I was thinking :(

Too close up and the variance would be too minor.
Too far way and it might be hard to determine if it's other influences affecting impact.

Although I suppose if you used a graduated target, and strapped your rifle to a lead sled, and didnt shoot but just viewed where the cross hair moved in relation to the target that would work.......

This.

Find somewhere you can point the scope 1000 yards. Take it off the gun and you could even use a back road. Mount the scope to something super solid that won't move as you adjust the knobs. Out at 1000 yards, pound a stake into the ground. Then carefully measure 10 feet, 5 inches and put another steak in the ground. Then measure again, this time 10 feet and 11 inches from the first stake, and pound another stake in.

Now back to your scope. Align it with the first stake. Then, without bumping it in any way, turn 50 clicks of windage towards the other two stakes. After 50 clicks, if it's aligned with the first stake, it's using the 1"@100yards model. If it's aligned with the furthest stake, it's using MOA.


My prediction: neither. And I'd bet if you picked up a dozen identical scopes, the variance between them would be greater than the 6 inch distance between the two stakes.

That's probably pretty true.

I was reading another site that said one might find near the center of adjustment it could be one graduation and as you work towards the outer limits, one might find that it starts to change.

Obviously, a nightforce or S&B would probably be a lot more consistent than a Bushnell ;)

there is bushnell and bushnell ... for a while nightforce (made in Japan) were build where sightron and bushnell were built also and among other brands ...

So what you do is combine the two, close range precision and controlled conditions, and huge adjustments. The increments will be what they are, but to a certain extent errors in adjustments can be compensated for by an adjustment in the program. A somewhat bigger issue is if the adjustments are consistent, first-time and everytime no matter what. Nothing but shooting is going to prove that.

A cost effective way to test a scope's adjustments and repeatability is to mount it on an accurate target .22 LR and burn up a half a brick of shells. A POS won't have anywhere to hide, and it won't take your barrel down with it.
 
Simple answer is probably the right one. Short of calling Bushnell in the states and trying to speak to someone with enough knowledge... I would go with 1/4" = .25 moa at 100 yards and call it a day, I would be surprised if it were anything else. Bushnell has a history of keeping things simple and "to general industry standards." I could also be wrong, but I don't think so, if I am that's okay too.
