Wanting to build a scope testing rig that I can use to test the tracking on the various scopes I own, and future purchases. Have seen some of the posts (some here) showing wooden clamp-down styles. Have also seen some pic rail tripod adapters.
Two main questions: considering I would want the platform to be 100% stable, I assume the collective would frown on the idea of a tripod mount, even with a super expensive, fancy tripod. If this assumption is incorrect, what tripod would be recommended for the purpose? Secondarily, although every thread I see tests at 100 yards or meters, is there any reason it couldn't be done at a closer distance? I have 20y available in my yard, and if I could make a testing target that was sufficiently detailed, to make up for the otherwise tiny reticle movement at such a short distance, any reason why tracking couldn't be tested without having to cart a bunch of stuff out to the range?

I am a fan of Manfrotto tripods and heads, have had great success with them.
And there is no such thing as 100% stable. At 20 yards, you have 2 primary issues: 1. Parallax adjustments on many scopes will not go that low. 2. You need a good target, very good glass, and an expert eye to be able to accurately evaluate movements in tracking. That becomes more true as range decreases. As a shooter rather than an engineer, my testing is done on a gun, where the scope should end up anyway. There are lots of tests for tracking on a gun, I would think the same would work on a static mount, you just need a well thought out plan and very good markings on your target of interest. In this, the math is the easy part; coming up with something that actually works well in the real world, that is the challenge, but plenty have done it.
