Sanity Check: 20MOA Cant Mount with Sig Sierra3BDX (40H/40V MOA adj)
#12
Ok, got the scope. Going to set it up on my 5.56x16" fraken carbine. While I await receipt of my new 6.5G upper.

The scope does indeed have only 40MOA of elevation and windage adjustment (160 1/4-MOA clicks, stop to stop).

As such, I am considering running the reticle down to one MOA off the bottom stop, and use a canted set of mount rings (Burris XTR Signature with various MOA ring-insert sets), and zeroing it at 100yds, slipping the turrets to zero, once sighted in.

The thought process is that the traj/poi will always be lower than the optical zero (except when shooting a target at 100 yards), which would nearly-always impute raising the reticle to push poi down. I'm thinking that adopting this approach, I should be able to get full use of the reticle's vertical field of adjustment enabling reticle-on-target out to the cartridge's 40MOA distance, and using hold-over for any distances from 40MOA to the bottom of the reticle's markings (or to the limit of the cartridge's Supersonic range, if less).

Does this sound like a reasonable approach? I can't conjure up a reason where I would want to have an ability to move the POI up above the 100yd zero'd POI (except for those rare instances where I may be shooting up or down a slope at a close target?).

Am I tracking true, or off muh rocker? What say ye?
