Back in the 80s JDJ told me that IMR 4320 was THE powder for the Whelen. I used it with 200 HSP for 2800 + in a 22" Rem 760 I had rechambered.

I should have added, that 200 H S P is also a HAMMER on WT. I've seen them knocked sideways upon impact. One buck stiffened up like an ironing board (if anyone remembers what that is). He stood more erect, all 4 legs straight as boards and he took a couple stiff legged steps......TIPPED over sideways.
I've also SEEN deer have MORE visible reaction to being hit with magnums, esp 300 WM, than lesser cartridges including 270 W.
