Would there be any risk to having a load around that light?
I use H4350 for loading all my 165gr to 180gr 30-06 ammo. I feel using 4350 with a 150gr bullet is a bad idea. 4350 is too slow a powder with such a light bullet IMO. It's my opinion you will get better results using 4895, Varget or 4064 with a 150gr bullet.
