I've tried both the 168 and 150 ABLR out of my 7 rem mag and have gotten them to group pretty well but haven't seen the velocity I'm looking for. Chrony set at 16 feet I was getting around 2800 fps with the 150s with N560. Around 2900 fps with the 168 but SD was 45 using 70 grains H1000. Norma brass and fed 215m primers. Best so far was 35 thou off the lands but still tweaking. I've read that they like a long jump tho and some guys are loading them at 90 thou with good luck.
