Elk is why Winchester made the Model 1886 in the first place.
If you can find them, the 350 grain flat nose is a tough bullet that was designed for the 450 Marlin Express. The 350 RN is too long to cycle in levers, that I owned.
The 400 or 405 JFP does a nice job and can be loaded pretty heavy for the 1886 pressure levels. I find Re7 to be a great powder for such loads.
