Scope Rail for Model 12 in 6 Norma BR?

[South Prairie jim]

I am setting up a new Model 12 in 6 Norma BR and plan to use a 105gr bullet & a Nightforce BR 12-42X56 NPR2 riflescope. Does anyone know if a "0" elevation, a "10 degree" elevation or a "20 degree" elevation would be best at 500 yards? I would like to be able to sight in @ 100 yards, but do not plan to shoot much over 500. We are limited to a max range of 600 yards here. My concerns are keeping the elevation adjustments in a reasonable working range. Thank you & safe shooting - oldwrench

i use a zero Moa rail on my 6 Norma with a 300 yard zero it takes 7.75 minutes for 500 yards and 10 minutes for 600 yards.
