Moose don't take a lot to kill if a good shot is made. Whitetail deer take a lot to kill if a bad shot is made. Over the last 25 years I've killed or been with hunters that killed more moose than my back cares to think about.Three were taken with bow & arrow.I'll try to list them the best I can ,1 with 243, 1-30-30,1-35 rem,1 20 ga slug,1-12 ga slug,1 44 mag. 2- 444,1 -45/70,several? with 30-06, about 6 with 300 win mag, 1 -338 mag.some I'm not sure of but. None went over 50 yrds, most less than 30 and a few were DRT the 30-30, 444,both and the 20 ga all fell on the spot. Does that make them the best moose guns?Or does it mean you make a good shot on a moose with most reasonable calibers the blood trail will be short?
