It's coming together for me to hunt each variety of elk this next season, with only Tule in Cali still a bit in doubt; and Roosevelt's at the short ranges likely in that coastal rain forest has me thinking they're a natural for cast bullet hunting.
I've been using some Mt. Baldy 270 FPGCs in my nice old 9.3x57, that I think would work well. I'm down to my last box, though, but I'm casting my own now and Arsenal and NOE both offer 10 grain heavier but otherwise very similar molds.
It's a mild mannered round, and cast shoot well at standard pressure and power. The round was designed for elk, even if that elk is really a moose.
My elk experience to date is all Rocky Mountain Elk, using Partitions and Interlocks.
Are any of you Roosevelt hunters, that'd share your opinions or tips?
