I got my first trad deer Friday here in CA, shot her @ 30yds with a VPA Terminator 200gr (AKA the non-vented WW Elite @ 3Rivers).
http://tradgang.com/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=1;t=081428 She was about 10ft above me vertically, spot and stalk, and my arrow entered a tad too tight, shattering the bones in the lower leg just below the elbow, going through the heart and lungs and stopping in the offside shoulder before being broken as she ran off.
I have no doubt that even though I hit bone going in, the only reason it didn't pass through the opposite shoulder was that she jumped and broke the arrow as it hit her, but that is my opinion.
She only made it 20yds, but every 3 feet was a huge spray that I could see easily from a distance under the canopy of trees.
I was very impatient and got to the spot of the shot to mark where she went into the thick brush, only to find her stone dead 20yds away.
Maybe a 2 blade would have cut through faster and passed through, but that blood trail was as good as I have seen with a pass-through and a 4 blade head.
That broadhead is still good-to-go, and is in my #1 spot in my quiver. I will hopefully give it a shot at a bear in the next week.
Good luck.
Also, upon inspection the broken section and the broadhead had worked to the top of the lungs in teh top of the chest cavity in that short 20yd dash she made before dying.
