that would be a spitfire by Nap. that is a 1 1/2 inch broadhead.the spitfire requires a lot of kinetic energy to make it operate. the neck is meaty and it will offer a lot of resistance to the broadhead and arrow, enough in your case to stop the arrow before it could pass through. Now it appears that the 1 1/2 inch size broadhead is to large for the amount of kinetic energy you have. you would have better luck with a smaller diameter cut head, and if you have to use a mechanical a rocket steel head, shockwave or scorpion by nap, rocky mt.sniper all required less energy to operate and all work well.
