Currently still working on this, but I ran a uni-throater in my 7mag to let me load these a little longer.
When I spoke to Berger tech he stated 63.4gr-69.7gr N570 at 2583-2876 FPS at 3.350" COAL.
Here is mine FWIW.
60.8gr RL23
PPU case
Fed 215mag
COAL 3.560" ish
I think RL23 is a little fast for this bullet, pressure happened faster than I would like. Have not chronoed as exploring N570.
69.8gr N570
PPU case
Fed 215mag
COAL 3.610" ish and 3.590" ish. .010" and .030" off lands respectively. Testing seating with these shortly.
This thread shows a deer shot with them.

Berger 190 LRHT, 7 Rem Mag, RL26
So we rethroated a Christensen Arms Ridgeline 7mm Rem Mag and have begun load development for the 190 Berger. We started with RL26. With no data available on the 190 Berger and very little on the cartridge with RL26 we just started with a quick pressure test. 65.0-2855 65.5-2855 66.0-2870...
