TA31-F ACOG with 16" Barrel and 77 smk?

[alan98]

I'm probably buying the TA31F acog for my RECCE build with WOA match 16" barrel and I use 77 smk's. Has anyone used this similiar setup? I'm just wondering if I'll be able to establish a zero at 100 yards that will carry out to 600 and be someone close to the stadia lines. I think I read like 1.7" high at 100 will be close all the way out?

Anyone have any experience with these?

Thanks,

Alan

I have used a similar set-up. The ballistics reticles work fairly well. However, the TA31F has a very short eye relief. It's not a problem for some and it bothers other (me).

Per data Trijicon gave me the drop in MOA for their BDC, which is normed to M855, is:

100m zero
200m -2
300m -5
400m -8.3
500m -13.1
600m -19.2
700m -27.1
800m -37.2

For a 77 SMK at 2650 FPS I calculated these equivalencies a few years ago and they work pretty darn good:

for use
100 100
200 200
300 300
400 400
500 400-500
600 500
700 600
800 700
