It was windy and a bit chilly but I was able to squeeze in some range time (more fire-forming and trying out the new muzzle brake).
I wasn't looking for any accuracy load at this time but here's what I got (3 shots at 100 yards) ...
(1) 60gr 7828SSC 150gr NBT, WLR , Win brass - X=3130 FPS; SD=24
(2) 60gr H1000 150gr NBT, WLR, Win brass - X=3044 FPS; SD=11
(3) 60gr H4831SC 150gr NBT, WLR, Win brass - X=3194 FPS; SD=4
#3 has the best X, SD, and group. No signs of pressure yet.
Sorry for the quality of the video (Panasonic Lumix DMC-TS4), I should have used my rest but I couldn't cradle it well and I figure it'll show the muzzle rise/recoil better if I use a shooting bag. Unfortunately, I forgot my rear bags :( ... might have to re-do the video next time. Anyways, here's my initial attempt ... sorry, not good in editing. I start getting steady about the :20 or so mark ...
I was using 175gr Matrix with 57.5gr H4831SC at 2919 FPS.
Overall, I'm very pleased thus far!
