NAP (New Archery Products) Thunderhead 100-grain Broadhead Review:
Very Affordable broadhead. I have shot over 5 deer with this head and I really had no problems with it. I am shooting a 60 pound bow and I had 3 complete pass-throughs on the animals with the other arrows ending up lodged in the deer’s chest. I recovered all the animals with no problem.
The broadhead has a 1 3/16" cutting diameter making for a decent sized hole and a relatively easy blood trail to follow. The reason that I switched away from these heads is because I wanted something with a little bigger cutting diameter, but overall a very nice broadhead that will defiantly get the job done.
