That's a big old bullet. I'll bet it does flip them in their tracks.
I've also tried H4831, Reloder 22, Reloder 25, Reloder 33, H1000, Retumbo, IMR 7977 and Magnum and they're all pretty good with the 130 gr AB or 142 gr LRAB, but Reloder 26 produces better accuracy and plenty of velocity vs the rest.
