In planning an archery bison hunt a few years ago, I wanted the best bow - arrow combination to harvest a 1500 pound animal. Buffalo are not necessarily afraid of people but it's very important to get close enough and get plenty of penetration.
I was currently shooting a Matthews bow set to 70 pounds and carbon arrows weighing in at a bit over 400 grains. I had harvested deer, elk and mountain goat with this combination, but was it enough for a large bodied, heavy boned animal. What was more important.... speed or weight?
What are your feelings? I'll tell you later what I used and how it worked.
