H 4831 is a med-slow powder in my 270 wsm. It is best behind a lighter bullet, like 130 g.
It is very accurate with a 135 smk and very consistent, but not very high velocities.
I suppose it will work behind a 165 grainer, but at 2500 to 2600 fps.
A slower powder like Magnum will push the heavy bullets better/ faster.
just my 2 cents.
