Hey guys,
We raise bison and "harvest" a few in the field. Some people call it hunting but even though ours are semi wild there's not much challenge to it. I've shot a 1200# bull with my 55# BBO longbow, cedar shaft, and 125gr head. thru the heart and he was down and out in 7 seconds, one other guy shot his thru the lungs with a wheelie bow and it went about 70 yrds.
I've had lots of experience with these guys and would not trust any buffalo, they are extremely unpredictable and dangerous.
Be careful out there,
Doug
