I had bad luck with these broadhead. I am glad to hear that people had good luck with them. I thought they were great while broadhead tuning, but when I shot a 6 pointer broadside 25 yards, I lost him. To make a long story short, I caught either the shoulder or a simple rib (i think the latter) the arrow defleted and lost all penetration and therefore I lost the deer. I have heard stories of blades coming open in flight and causing the arrows to miss or wound. In my opinion ... its a give and take with ALL expandable broadheads. I think you pick up accuracy and confidence using them, BUT have little room for error! Catch the wrong spot on a deer and expandables will leave you tracking for hours with usually no luck. I have heard and met dozens of hunters who love them and others like me who hate them, because of the same stuff. I hope they work out for you but this hunter would rather tune for hours and spend the extra money on trying different fixed blades, then loose a deer due to expandables! Not a big fan, sorry!
