Which 20 moa rail

[yobuck]

I've got 20 moa EGW bases on 3 guns (22-250, 308, 6.5CM) and a 60 moa Farrel base on my 338. No issues with any of them.

Interesting, What zero distance and what 338 may i ask?
My son has a 40 minit on a 338x378 with a Nightforce 8x32 nxs and he can zero at 100 yds, although right on the bottom.

I'm on a 40 MOA EGW base with a Razor Gen II HD on my Lapua, but the bell housing is sitting almost right on top of my hand guard. I'm able to zero at 100 yards with a little room to spare.
