Don't overthink it. Moose die easy IME ( 20+). Those eastern are quite puny compared to Yukon-Alaska.
.243, 30-30, 270, 30-06, .338 WM, 12 ga slug. Not in any particular order. Gonna try the .260 next if possible.
It's where, not what. They just take awhile with most anything except CNS. BTDT too.
OK- OK - once a spike took 4 250 gr. .338 WM before he went down. 3 if you don't count the knee shot off with the 2nd round. The other 3 exited on the far side of his lungs through basically one hole. Entry wounds were quite un-similar. All were fatal on their own.
