I was baffled when I found the arrow and more baffled when I found the carcass the next week. The broadhead had two blades, the o-ring was still on the blades.

Now that I think about it, it's possible that i was not at full draw at the time of the shot not providing enough energy to open the blades. Although that seems unlikely since I wouldn't have gotten back to my anchor point. I don't know. Too long ago to dig up the details from the archives.
