A leetle more R&D in the books...Castin' & Blastin' today.
A 50yd zero,granted 23.1 Mils remaining erector travel,ala 25MOA extended DIP 1913. Sister had the hot hand and sluiced a coffee cup at the 550yd line,while chasing some wind. 20Mils on the erector,the balance on the reticle.
After running up and down the total erector travel scale,dozens of times(burned only .2MIL windage,from mechanical center,to establish zero)...it printed back to where it started.
Initial impressions are more than positive,though I'm craving a 50MOA extended 1913 rail,so as to eek more goody.
This NEF seems to shoot.
