My father in law and I went buffalo hunting this past monday and took two nice buffalo's. His was approximately 1900 lbs and mine was approximately 1200 lbs. You can see the difference in the size of the heads, but mine had remarkable horns for his age matched that of the larger buffalo. The pictures are below....
The pictures are huge so here is a link if they are too big to view

I have a video of the hunt with the bow and arrow and a video of my hunt with the 45-70. I will try to get a video of the bow and arrow hunt on the internet. You can see the flight of the arrow really well and see the impact into the bison. its REALLY neat to watch. I will try to get it up as soon as possible.
