Here's a couple of quotes from MD I saved a while back:
Have always used one of the 4350's for 165, and still have no reason to
change after perhaps 20 .30-06's. But have found Ramshot Big Game
really great with 150's (it is not quite as slow as the 4350's) and lately
have found Ramshot Hunter fantasitic with 180's, with tiny groups and
muzzle velocities of 2800+ with standard loads.
H4831 with 200's has worked well for 30 years or more, in many
.30-06's.

I mean 58 grains. Have tried this loads with various bullets (180
Sierra, 180 Nosler Partition, 185 Berger VLD) in three different '06's so
far and all shoot as well or better than they do with any 180, and muzzle
velocities have been 2800+ in every rifle.
The rifles: Modle 24 NULA, pre-64 Win. Model 70, and a Sauer 3000
drilling made in 2002. The first 2 have 24" barrels, the drilling 25".
Actually, no powder is totally temp-insensitive. Many are pretty good
in cold temperatures, and gain less pressure (and velocity) in heat. Big
Game and Hunter are about as good as anything I've tested, including
the Hodgdon Extremes.
VV 550 is a very good powder, as are all the VV's I've tried. But I can
get Ramshot a LOT eacier around here....
been meaning to play around with Ramshot Hunter this summer to see what gives...
