Here's the loading I wound up going with.
Remington brass 1x
Ramshot Magnum @ 68.0 grains. Will be good for 2700-2800 fps
CCI 250 Magnum primer
Hornady 139 grain Interlock.
I'll shoot it & report back.

Put 3 rounds into .600" off the bench today starting with a cold clean barrel, as the barrel heated up the groups opened up to a little over 1 MOA. This load is 7 full grains off maximum so it's pretty mild one in the big 7mm.
Moving the 139 grain Hornady at 2800 fps its operating like a 270 WCF with similar recoil. I'm impressed with Ramshot Magnum powder it meters like water & is quite accurate in reduced loads
