I will be on a moose and bison combo hunt next september in BC.. I will also have a Mountain goat tag and will def go after a group of goats if we see them..Both will be shot out of a 80# bow
arrow 1- Easton Axis 260 50 grain insert 125 grain tip total arrow weight 550 grains.. silver flame broadhead.. Speed 265 FPS
arrow 2- Easton Deep six fmj 20 grain insert 100 grain tip total arrow weight 450 grains.. Solid broadhead... Speed 290 fps
Arrow's trajectory would be flatter, thus increasing margin of error for distance measuring.
I know heavier is better, but at what point do you enter the realm of diminishing returns?
not to say 2 would be insufficient, but you asked which of the two. You are hunting a really big animal and a really huge animal. base your decision on that. The goat will die with anything that will kill the other two.
I hunted with Mike and Dixie last year for Moose and Bison. My arrow weight was 510-520 grains and my speed was 317 fps. My moose was shot at 31 yards, my bison was shot at 46 yards. On both animals, the arrow just missed being a complete pass through....getting hung up by the vanes in the fur on the back side of the animal, after hitting at least one rib in both cases.
Either set up is adequate to do the job.....though most people agree that the heavier option is the preferred choice because of the momentum.
My shoulders are beginning to tell me that I should have updated to a newer bow years ago, that could deliver the same KE, with a substantially lower draw weight.
Brandon.....How's the coffee?
