I have a custom build coming in a few weeks.
Barnard P action.
Scope is Sightron Siii 8-32x56 75 moa total adjustment
Would like to zero @ 200yd and potentially shoot to 1200yd

Barnard makes 17moa, 25moa, 30, 40 and 50.

Which rail would you suggest?

Thank you.
 
I'd go with 25, or 30 if you are feeling greedy. Anymore and you might have zeroing issues depending on the natural PoI of the rifle.
 
I'd go with 25 as well. I dunno what caliber you're shooting but 75 moa is roughly 29 mils so depending on where you zero you get say, half of that gets me past 1300 yards with a .308 shooting 175s. Add on the extra 7+ mils from that 25 moa base and I'd be astounded if you weren't good to go 1500+

I'm gonna be shooting .284 win.

Assuming a flat rail will zero at exactly the middle of your adjustment range, so 38 up, 38 down.
17MOA rail = 55 up, 21 down
25MOA rail = 63 up, 13 down
30MOA rail = 68 up, 8 down.

If a flat rail will zero at exactly one third of your adjustment range, so 50 up, 25 down.
17MOA rail = 67 up, 8 down
25MOA rail = 75 up, 0 down
30MOA rail = 80 up, -5 down.

For reference, hitting a mile with a .284 will take about 60MOA. The 17 moa rail will work fine.
