As some of you know I shot a nice buck this week. I wanted to let you know how the NAP Spitfires worked. I've read a few threads on here where people said they didn't open. I'm not shooting the MAXX just the standard with chisel tip. 125gr. I shot my deer slightly quartering away at 22yards. I did not get a full pass through (kinda). My arrow was buried to the fetching with most of the arrow sticking out his left side. The blood trail didn't start for 50 yards but then it was like a river. Especially when he broke the arrow off. Flight 10/10 Blade Deployment 10/10 Penetration 8/10 Blood Trail 9/10 (would be 10/10 if I got full pass through) These are a great head, this is my first year with this head and I will be using them for years to come. I shoot 60# draw and a 29" draw length.
