Wow. I can’t touch that with surplus H4831 and GI brass. I think 58 grains was all I could stuff in a LC Match case with a 200 gr. NPT.
Something to try.
I use a Long Drop Tube to load max capacity powder in some cases.
4831 and 7828 are 2 that I use that fills the 06, & 270 W cases.
Might work for you.
