What's cartridge, velocity?
.30-06
Likely 180-220 grain Nosler Partitions. So say 2400-2600 fps?
Just call NECG and they will do the calculation for you.
I think that I can't specify the rear peep yet. Also the vagaries of mounting a peep sight on a Weaver base will affect the height somewhat maybe.
So I guess I'm looking for what the historical norm for front sight height from barrel to top of bead, and will add a little to that.
One idea is the Skinner 860 on the back of the receiver, and an Aimpoint Micro on the front.
The other is a full Weaver bases with a weaver mount NECG or XS peep sight at rear. Then I can mount a scope on QD Warne rings and swap between scope, Aimpoint or irons whenever I like, without tools.
