I had two out of three fail to open at less than 10 yards. So two is enough for me to never use them again.
But they do fly pretty good so if you do choose to go for them that's a plus. Tim Gillingham tested the NAP Killzone with the trophy tip out to 120 yards and he said it was the most accurate he's ever tested and that's all he uses now.
I know a lot of people that use them with great success. I know Shane has had some problems but that seems to be the exception more than the norm. I don't use them, I use QAD Exodus. I bought some Hypodermics and practiced with them, but my bow is tuned and shoots the QAD's great so I just keep using them. But I am not a mechanical hater if you have the proper setup for them.
Your bow is out of tune if you can't get fixed heads to shoot correctly. Sent from my iPhone using Tapatalk
@bucksnbears when i first started shooting a bow i got a package of the put together kind of muzzys, i found they plain real bad Sent from my iPhone using Tapatalk
Hypos have some of the weakest blades on the market. They will snap at the collar notch, even without hitting bone. Had it happen personally and seen it all over the web. It is a design flaw. That being said, even if both blades snap off at that point they are still a 1.5-1.25" cutting diameter head and inflict serious damage. And they fly like darts even in a poorly tuned bow, if you are so inclined to shoot that way. Don't worry about the practice heads...Hypos really do fly just like field points. Of course, so does most any quality fixed head out of a well tuned bow, but that's a topic for another thread. Like a thousand other threads.
Be sure to line up the o-ring and blades correctly. You almost need a microscope to see the arrow sketched on the back but in essence, you want the base of the blades in the middle of the splits on the o-ring. They say it will still work if you do it wrong but I don't really want to find out.
