Anything slightly heavier that won't break up will knock over a moose
This! My hunting crew and I have knocked down a mountain of moose over the years with .308s, .30-06s and 7mm Rem Mags and none ran further than 30 yards. I killed my 52 inch bull with my .308 and he didn't get that far. It's what I'll be hunting moose with again this fall.
For what it's worth, my warthog ran farther to a perfect shot than any of our mooses!
