In case anyone is not aware 5spot does broadhead testing. He test various things like sharpness, accuracy, durability, and penetration.

Well the new NAP Nitron and Crossfires passed the test with flying colors. I believe the Nitron scored the highest points of any head tested.
Full penetration of a 55 gallon drum both sides no damage to the head.

Now that's penetration and durability if you ask me. Should you be slightly off and hit a shoulderblade it should go right through.

I may have to re-think the good ole standby muzzys
