This is from one of our staff guys up in Wisconsin. He did a pretty good job of documenting the entire experience from shot to blood trail to recovery and post-recovery inspection. For those curious about the BloodRunner's performance in the field, this one's for you. http://www.bowhunting.com/blog/post/2009/10/06/The-damage-of-NAPe28099s-new-Blood-Runners.aspx
Nice blog and glad to hear the heads held up so well on a shoulder...although I'm extremely happy with my muzzy's, I will say I respect NAP products, attention to detail, and blade sharpness/strength...I would not hesitate to use NAP broadheads... ...nice shot
I'm using Spitfire MaXX's right now. If I shoot something, you'll be one of the first to know! And no, they don't sell replacement blades but they do sell practice heads now.
