I' m just curious.......What KE level do you have to worry about shooting through a second deer standing behind one your aiming at? My KE is about 63 and I am getting fabulous penetration with a 1 3/4" mecanical Wasp Jackhammer. Two buddies of mine, just got Bowtech VFT Samson 80 lb. rigs. Their KE between 89 and 91. Holly Cow!! Just curious.....should they be worried about other deer in the area?

Good Luck!
