If you look at the high speed camera footage of the shot the carbon will recover much quicker from paradox with much less oscillation than wood and then when the arrow hits the target the carbon will have much less vibration/oscillation than the wood thereby putting more energy into penetrating.
Thank you all for sharing your wisdom and experiences with regards to my question. Very helpful!
I do find the point made by Mint here to be quite interesting. Behind my Block Vault I have a sheet of 1/2" plywood. (I aim close to the edge of my target of my target at times to make use of the entire target face, so the plywood saves my basement.)
When I have a wild shot, most times it will pierce the plywood if I am shooting my carbons. But my 11/32 woodies (at about 510 gr), have always bounced off (except for one shot which may have hit a pre-existing hole).
So Mint's comment here makes sense in light of my experience: that upon impact the carbon arrow will vibrate much less, providing more energy to be retained for penetration, even though the woodies are much heavier.
I have some GT "Fact" internal weights on order. Once I bring one of my carbons up to 500 gr, I'll do some penetration tests, both with my target and with plywood.
All that being said, it's good to hear that a game animal provides enough natural "lubrication" to allow easy pass through with even tyick woodies.
