Hornady told me they us H110 in their factory 200 grain ammo.
(I have since found this to be false (june 2018)
I pulled bullets from 20 rounds and powder weight was 52.1 grain average.

I believe they list max as 52.7.

Load at 51.2 grains and get right at 2200fps.

Starting at about 50.2 grains the increase in velocity is very small as powder is increased.

This were I typically load at, don't see any difference in group size, at least with my shooting.

Be safe.
