Just my 2 cents...
The H4350 gave plenty of speed early, but usually means it's running hotter and you won't have the case
fill you want. If you have 75% case fill, will usually result in variations in velocity at distance.
Varget, wouldn't even try, to fast of a buring powder. For heavy for caliber bullets.
H4831, possibly. Had some but didn't try cause I found a couple others to work with.
IMR4451, same as H4350.
RL15, about the same as Varget I would assume. To fast.
RL22, might work, about the same as RL23. RL 23 is having a lot of new followers, and working.
Someone posted earlier that they liked the 7828sc. Would be a try.
The VV N560 is a double based powder and runs Hotter than most. (burn your barrel up sooner) I would try the N165
Out of the ones you listed, in order.
7828sc
RL22
N560
H4831
I started with the 90g SMK's, they price them by the 50 count.. Very costly bullet for some reason. WTH
Even the 95g are cheaper than the 90's
Using the Berger 90g now.
