I have hit squirrels in the butt with HTMs that did not seem phased at all. I have been hunting squirrels and bunnies and pheasants with bows since I was in grade school, I have killed a lot of game with blunts, HTMs and bludgeons. I have killed quite a few with free three blade broadheads as well. We cut notches into the hi-precision heads to make them more effective on small game. The vitals on small game are small. We occasionally lost game hit with sharpened broadheads. 9/16" blunts are legal for turkeys in Iowa, I think other states as well, I had extreme doubts about this, so I called to get to the bottom of their reasoning. The person that I talked to had stats of the testing and lots of information. He was very insistent on its effectiveness. Crossing over from his logic with large blunts to squirrel hits. You hit a squirrel in the butt with an HTM you may give it a bad day, but he will live to tell about it. Change that hit so something more than a glancing butt hit, the squirrel is dead. Make that glancing butt hit a sharpened broadhead, you are still not going to stop the squirrel, but you have given that squirrel much more than just a bad experience, more than likely a life ending gash. Was it Saxton Pope that wrote that the shocking power of a blunt seemed more effective than a broadhead on small game? It will always be part of the game, you still need to hit them right for the cleanest possible kill. Saying all of this, I did get another free six hi-precision heads this week. I hope to get a pheasant or two with them.
