With the 150 grain bullet being just shy of the middle of that weight range, it validates H4895 as a good candidate. A powder that works well at reduced load levels is desirable here, and H4895 fills that bill, too. However, case fill for H4895 at the Hodgdon maximum (44 grains) is only 82%, so a magnum primer may give better velocity consistency with it. Both 4064 (45 grains) and Varget (46 grains) give about the same pressure and velocity in QuickLOAD, but fill the case closer to 88% and will therefore be less likely to be improved by a magnum primer. All worth trying to see which one shoots best for you and fouls least.
