Home Forums Hunting & Shooting Hunting Optics Scopes.............

with the precision you play with in mind what Scopes in your experience make the better list and what Scopes make the not so good list as a general rule..

No picture of the target with the markings?

So you’re only able to test MOA reticles and scopes?

What distance from the scope do you set the “target”?

I do alot of load development at 500 yards.
Couple years ago on the way to my test range got about half way there and remembered I didn't have the paper I usually have.. crap.
In the middle of July in the middle of nowhere is a Dollar General. I pop in and find of all things Christmas wrapping paper.
Santa clauses on one side and the 1 inch grid in white on the other. Just as you described.
Grid showed up just fine on my target vision camera.
Worked great..

Al;
Good morning to you sir, I hope that this Christmas Eve morning finds you and those you love well.

Thanks much to you and handgunnr for showing the scope testing jigs you've made up, it's given me a few ideas to refine the apparatus I fabricobbled together to test if used scope we pick up will track - or not as is sometimes the case.

Your quote that I've put in bold reminds me of something my late Father used to say to me, especially when I was younger and wasn't sure about trying to fix something on a dirt bike or gun I had apart.

Not to say I was or still am always successful in my repair efforts, but its always an education.

All the best to you all, Merry Christmas and Happy New Year.

If you’re going to go to the trouble of making a fixture to simply hold a scope, why not make a fixture to hold a barreled action AND a scope?

Because making one with just a rail to use testing a scope is exponentially easier than fabrication of any even semi-universal action jig?

Or you could just C-clamp it to the merry-go-round at the local playground.

Probably, but if one is so interested enough to go to the work of making the scope fixture and cares about scope functionality, it would follow that they would be concerned about mounting a scope on a rifle with the same care

Al, thanks for the good laugh, that is absolutely hilarious.

That has nothing to do with one's fabrication capacity. One would be easy on my shop, the other not so much. It has nothing to do with what I "want" to do. Making a jig to check a scope's tracking with a welder and some time is easy for anyone with a welder.

Not being able to whip out an action jig in your shop in an hour doesn't mean you shouldn't whip out a scope specific jig.

I've learned a lot reading this thread. Some of it important and the rest, the "fine art of one-upmanship".

Shooting live ammo,ain't as scary as it sounds. Not all wares are equal,nor even close. Hint.

To be continued. Hint.........

I agree with Rick. Static testing a scope on its own is good for seeing if it's worth mounting in the first place; however, in a lot of cases, the scope trouble is caused or exacerbated by the way its mounted. Therefore, testing a scope after it's mounted to the gun on which it's going to be used offers much more utility. Likewise, getting a scope squared up correctly in the first place saves a lot of time and ammo when doing TTT and other types of actual shooting/testing to make sure a rig is RTG.

Nice. One of the main reasons I say static scope testing tales lead to some of the best optics threads.

I need to build a micro-adjust jig to zero out the coriolis effect of a static tall target test depending on whether I'm shooting N, S, E, or W. I mean the target isn't even located where you see it, it's moved by the time you see it. You can't shoot a TTT where the target is, you have to shoot it where it's going to be.

I'm surprised none of you even realize that all you're ever seeing through the scope is where the target was. Good Greif.

Most of the time, when I pull the trigger where the target was and where it is relative to me are the same. Unless you’re observing from off planet?

Not as nice as Al’s, but a static rest is pretty easy to build. 3 legs and a Davidson or Picatinny base mounted to a flat surface and you can tell if a scope is a POS before you bother mounting it. Does the reticle move with the clicks? Does it freeze and then drop after 4 clicks? Etc. This (or a collimator) also tell you if unsaddled with every variable that a rifle, mounting, or conditions -does this scope track accurately? is the reticle canted from the adjustments?

If it tracks accurately you have a baseline—the scope is capable of aiming a rifle accurately. Then introduce mounting, recoil and all the other [bleep] and see if it holds up, or try to figure out where you [bleep] up.

I would blame the scope last

Great example. 👍-Al

That's why it is well-worth checking to make sure the reticle and erector axes are aligned while testing tracking and RTZ. By fixing the scope so that the reticle is aligned with a straight line, and then running through the adjustment range of the erector, one can easily and quickly confirm that there is no deviation from the line as adjustments are made, and that the reticle and erector axis are parallel.
