UPDATE: I shot the 69.5 grns Hybrid 100V ( in Rem case, Win. LRP) with the 180 Nosler today.
Consistent groups at 100 yds of .75 and .875 between centers (4 shots each). Chrono'd at avg. 2976 with 10 rounds ( Hi 3000; Lo 2966) .
I intend to try the Magnum primers and see if that is different. And maybe up to 70.0 grns. (max is 70.2) to touch the 3000 fps mark. The down range ballistics will work out from there.
ALL YOUR COMMENTS ARE HELPFUL........THX
