Default AR Platform 50 Yard Zero Vortex Razor HD Gen II 1-6x24 SFP JM-1 Reticle, Discuss

Okay, lets get this out of the way, the 20 MOA Cantalever Mount on the AR platform, as far as I can tell, has zero affect on the shooter's aspect, or zeroing the rifle.

So I decided to go with a 50 yard zero on my preadtor hunting rifle set up (Vortex Razor HD Gen 2 SFP 1-6X24 JM-1 Reticle, mounted on a Vortex 20 MOA Precision Cantalever Mount, on Barrett REC-7 DI Carbine AR.

This day the wind was blowing left to right, 5 to 10 mph. Using American Eagle Factory ammunition (5.56 55 GRAIN FMJ 3165 fps), I took 11 shots at a 200 yards (I set this target upside down, lol). The shots hit left of center, you can see them on the target. I don't have a spotting scope.

Then I took 10 shots at 360 yards, there was a rock in the box the that some bullets splashed on shredding parts of the paper target. But the majority of the shots hit bottom right, some hitting the box and paper target, a couple grazxing the side, and the rest in the sand below. I could hear the impact report from the rock, it took about 2 seconds to reach my ear.

Now I need to find out which reticle elevation subtension hash mark to use at that distance, then when I get it right annotate that into my DOPE.

How do I annotate the windage, please see the 360 yard target (l to r wind, 5-10 mph, windage correction: 6 inches left)?

Like this?
Range: 360 yards
Wind: 5-10 mph, l to r
Adjustment:
Elevation 6 inches up
Windage 6 inches left


I need a spotting scope, which economically priced one to see shots out to 400 yards?

I picked up a Konus spotting scope recently, seems good for the price.

Thanks, I'll get a Konus. I'll use the Vortex app to design my windage adjustment, I currently do it the old Kentucky Windage style.

It's bigger in person than it looks online. Doesn't bother me because it's purely for range use. Clarify and light transmission has been excellent for the price.
