Rather than fiddle around with adjusting the ghost ring for height - I was going to use as follows (much easier and quicker to change out the front sight than to try and remember what the rear sight was screwed down to - there's no graduations on the NECG sight adjustments):

7.5mm bead on 458 for 350gn jacketed projectile loads
8.5mm bead on 458 for 325gn jacketed projectile and 500gn lead projectile loads
8.5mm bead on 375 for 350gn jacketed projectile loads
9.5mm bead on 375 for 270gn and 300gn jacketed projectile loads
9.5mm bead on 458 for 405gn lead projectile loads
10mm post on 375 for 220 and 235gn jacketed loads
standard CZ bead on 458 for 400 (spot on) and 500gn (a bit low) jacketed loads

I've adjusted the 10mm post and one of the beads (meaning I've filed down the base so it fits), can't remember which one, but I remember it was for the 375 - I'll research which one it was.

I've used many different loads for the 375 with a scope and have the setting adjustments written down. I did some trigonometric calcs based on this when I selected the front sight beads, and the post and bead that I used performed as expected.
