Re: IMR-7828SSC and 208 A-Max
Ramshot Magnum has been a stellar performer for me as well & I think it deserves a serious look.
As far a burn rate goes, it falls smack in between H-1000 & Retumbo, meters great.... If my 338RUM decides it doesn't like Retumbo, Magnum is next.
...I also used 7828 in the RUM, Worked great...
if bullet weight falls lower than that 208 I'd say 4350... In al reality, if you already have the ssc, just give'er a whirl, it'll either like it or hate it...
