Is this the pod that you're talking about?

And DC, you're right - it doesn't seem to be disputed that Fred Bear supported and may have developed a poison-release mechanism for a hunting application.
Funny how the peanut gallery was silenced when Fred Bear's name came up, eh? LMAO
That is not exactly what Im talking about when I say pod.. A pod is basically plastic with little pockets that hold the powder. The end of a balloon is placed over the pod and when the arrow strikes the animal, the balloon rolls back, allowing the powder to enter the blood stream.
Before the pod was invented, hunters used a broadhead that looked like a big needle. When it hit the deer, it would inject a fluid.. I have no experience with that, but have seen several of them...
The use of poison was in its hayday prior to the invention of the compound.
