For my #1 my load is right out of the Hornady manual.
Back before DGX Bonded, I loaded 82.3 grains H4831SC for 2050 fps. When DGX became bonded I backed off 0.1 grain for the same MV.
It's accounted for 1 cow elk in the scrub aspen between 35 - 40 yards, and 1 black bear too busy feeding on hazel nuts to notice me at just a bit over 100 yards.
Those older 400 grain softs killed regular stuff good!
Folks have said R15 results in less recoil, but I never could tell the difference, so I've stuck with H4831SC
I've been holding on to my Weldcore stash for the someday double...
