JD, I have tested that load in temps from 70 degrees down to below 0 and from sea level to 9500 ft and it has remained very consistent ! I did find the 168 ABLR to be more finicky in my gun especially with seating depth and powders...I had given up on it a few times ..one thing I don't like...
JD I'm running that bullet with Ramshot Magnum 66grains With a Fed 210M in nosler brass at 3.395 OAL..pretty much prints .5 MOA if I do my part..The 150 ABLR actually shoots better in my gun but I would rather hunt with the 168 for a little extra weight !
I hunt with the 168 ABLR in my 280AI at 2950 fps, So far it has been a killing bullet on 2 Elk...I would like to try some of those 150 etips they look like a good bullet !
