Thanks for the response,
I know ramshot magnum isnt listed on barnes newer published data. I do however have what i believe is older data that lists the 175lrx and that powder. The powder seems to burn very clean, and is shooting well from what i am gathering. Their testing shows a 24" barrel.
My barrel is a 26" 1:10 twist. The 200lrx requires 1:10 twist or faster. I went out on a wim with that 200lrx, knowing i could fall back on the 175. The 200 is a crazy long bullet. I was after that extra bit of BC while staying copper.
I live and hunt in california right now, so if anything the temps may be just a bit cooler during hunting season.
Ive got 10 more rounds of both the higher and lower charge 175lrx loaded up, and hope to test them next weekend at distance while gathering some more data on the chrono.
