It really does depend, JRW, if the woodchuck, would chuck, all the wood he could chuck.    

Penetration has been covered, more than a little by Dr. Penetration (Ashby) himself. Have a look at his report on this site.

jaz i can see how that tusker would hang up, and maybe both arows flew well but the heavy one was just too heavy for optimal preformance out of your setup, and yes evry one is right boards are not flesh but neither is bone, animals are as inconsitant as it gets when you talk about densities.  hopefully with a single bevel tusker that it will have rotated enough in a scapula to open a lane for the ferrule,
 
geez steeve thats a pretty strong post, must have a pretty big chip on that shoulder,  i thought this was a fairly civil thread,  your just going to get it closed and we wont get to see any development im sure jaz would like to further his experiment, and i would like to hear about it.

Jaz  that board recipe is pretty good actually.

easy boys....  

"amazing how easy it is to start a argument on this sight"

You're kidding...right?   :confused:

What Charlie said.

Also, nice post Jaz.....and yes, regardless, any test like that will tell you something....and I'm sure this one did.

I did some testing long ago....and I'm still using  what I learned.  I learned that I can run a wide 4 blade slap through a whitetail time and time again.....so, that's what I'm going to do regardless.     :D

Take care sir...and hope to hunt with you again sometime.  

Ya don't need a PHD to figure things out either....

BTW...I'm still waiting, after all these years, for George to show us a dead animal.      :D

Ouch Terry, the point on that one was sharp! j/k lol.

Howdy Terry. Maybe I'll see ya again at the PBS banquet.
