All done with homogenous solids and magazine-rifles I presume, so anything from .404 or .416 up to .458 Lott/Wells/etc. When culling I understand that the average size of the quarry would be much smaller than when chasing trophy bulls only.

Just my thoughts, mind, not likely to ever be wading into a herd of jumbos myself!

Most ele in the past would have been culled with the .375 H&H, .404 or .458 Win Mag with steel-jacketed solids.
