My experience is the scope is always a few MOA short of their claims. The only exception I've personally seen to not being short of claimed is my ATACR 5-25x, and that was on a 30MOA base with 30 MOA Spuhr so the combo might have been a few degrees short of a full 60 MOA in the incline. So I wouldn't count on getting a 100 yard zero is a 60MOA base.
If you're in this for a CheyTac already, add up the cost difference between an 5HD, ATACR, Razor Gen 3, TT, Khales, ZCO, etc plus a Charlie, and then look at the March Genesis. You're edging up on $5k+ for the scope, good mount/rings, and a Charlie plus mount even if the scope is only $2500 of the total cost. That puts you in the same price range as the Genesis with built-in mount and 300/400 MOA of elevation. Honestly the March isn't as good of glass as a TT, but since you're always centered in the tube there's no chance for image distortion at the extreme ends of the adjustment range.
I have Tremor 3 reticles, I like Tremor 3 reticles a lot, but mainly for speed shooting closer in. I don't see a ton of them in PRS but I use one for that. For ELR I want clean MIL/MOA grid marks and no overlay like the wind dots and numbering for movers in the Tremor 3. My Genesis is the FML-MT reticle that has .5 mil grid x-mas tree out and down to 2MIL under the center dot, plus hold-UNDER with a 4 mil wide wind line at +2MIL above center.
My brother likes his 5HD w/ Tremor 3, I've shot through it and it's a good scope, but not my thing in ELR.
