Ok folks, I am in no way associated with NAP. Nor am I an expert on archery equipment, however; I do have a bachelors of science in business administration so that should qualify me as a scientists... right??
Anyways, I just got the Killzone's today and did a little testing. I only used one of the 3 broadheads provided.
Equipment: 67 lb element RKT 27.5in dl VAP 350s
Out of the box Notes: Sharp... very sharp. Good looking broadheads with a very nice opening mechanism.
Accuracy: They are just as accurate as any other broadheads I have shot. They are not extremely forgiving but if you have good form and a good shot they will hit their mark.
First shots- The first couple shots showed that they were opened almost halfway on entrance through the cardboard
Then I removed the cardboard and shot into my Rhinobock
Then put the cardboard back (Note: The whole right above is from a g5 striker. Same POI much bigger hole with the NAP.) (40 yds)
shoots straight. (I realize it is to the right of the FP's but most of the shots were pretty straight when I held well (40 yds)
Accuracy: I would say they are accurate, I took more shots then I provided with pics and they were hitting pretty good at 40 yds.
Noise: I think they are a little noisy. Not as much as slick tricks.
Penetration: Hard to tell without a new target. They were reaching to the back of the rhinoblock. Not quite as far as the strikers.
Durability: After about a dozen shots there was some wear on the broeadhead but still shot good and opened on impact. (notch in bottom center of ferrule is from a fieldpoint) (not the best pic)
My theory as to why it was not opening in cardboard right away is that the little black screw holding the blades was too tight. It loosened a little. I would recommend making sure it is a little loose and I always test my BH's so just make sure they are opening on impact.
Would I shoot them: I sure will. They will be used on some deer this year and I will see how they perform.
Have a wonderful weekend brothers.
