My loading manual only shows info on 145 and 160gr not 150. I need load info for h4831 for the 150gr bullets. Thanks for any help.

Split the difference, minus a pinch.

AAdams,
7mm 150 GR bullets:
From the Sierra manual-- H 4831 SC 57.2 - 63.2

From the Nosler manual-- H 4831 SC 61.0 - 65.0

Nosler stated that this was the most accurate powder tested in thier gun.
Hope this helps. Good Luck. Mark
