I have killed a lot of hogs, I have used MA3& MA2 heads, Magnus 2 blades, Zwickey 2 blades, and now Wensel Woodsman heads.
It has been stated earlier in this thread, if you are shooting low poundage, which to me is 55 pounds to 40 pounds, on hogs get a two blade head, razor sharp, in any configuration I have listed.
If shooting higher poundage, I have a hard time grabbing anything other than a Woodsman. I shot through the spine of a pig season before last at 18 yards. The head came out the chest of the pig, and there was plenty of blood.
Only broadheads of solid construction should be used, leave your replacement blade heads at home. Hog hunting requires the very best, and the toughest.
