Elkass, you know, you're one funny dude at times and I know you like to stir the pot. I ran across this post last week but didn't have a chance to chime in until this morning.
To the OP, in my opinion the Nap Killzone is the best mechanical broadhead out there. It has a devastating 2 inch slice and as far as I'm concerned the best locking closed method ever designed. They are also rearward deploying which eliminates any kick out issues on quartering away shots. I have tested a LOT of mechanical heads and I can't say enough about the Killzone so long as you have the proper set up. Take care of the Killzone and keep them clean you will have no issues with it. I would not hesitate to shoot a huge bull with this head.
To swbuckmasters point, I have witnessed the very things in the field he has with the rage head. I cant stand a rage but it isn't for the lack of penetration issue. Those that have no pass through shots are shooting a wide cutting mechanical head with too light of an arrow for pushing those wide blades through. That's the bottom line. I shoot 455 grains minimum total arrow weight. I have yet to fail in a pass-through shot with in the last 10 years. It took me learning the hard way that you need a heavy enough arrow when shooting mechanicals as you NEED the momentum to push those wide blades. BTW, if you modify rage heads to stay shut during flight or stalks in the field then they're not so bad so long as you have a heavy arrow!! But unless your sitting in a tree stand or a ground blind you're going to have issues eventually. I think the new extreme rage has addressed the o-ring issue but I haven't played with them yet to know.
Now Bobby, please don't get a hair ball at the things im about to say. I can already hear you hissing and spiting, ha ha ha LOL, JK. Do you shoot a compound bow? Do you know ist is mechanical? A compound bow has many moving parts as any mechanical broadhead out there in the market.Can and will fail?? Well so will your bow if you don't take care of it and keep it tuned up. If you shoot enough your constantly looking over your bow. Mechanical broadheads are the same way. You have o-rings or rubber bands, change them every six mont as they do go bad/dryrot. Check to make sure they function properly before you go out in the field.
I am not a fan of any forward deploying heads or wing blade deployment. But mechanical broadheads have gotten a bad rap because of the operator more than anything else. They have also come a LONG way sense the first heads came out, just like the compound bow has. But if you're a speed freak, don't shoot mechanicals because no amount of speed is going to help push those heads completely through an elk.
Lastly, I don't mean to offend with this statement but if you are so ignorant about mechanicals that you can't clear the foam in your quivers then you don't even deserve to make a comment on Mechanicals heads good or bad. Learn how they deploy and then take a good look at your quiver. I remove the foam or open it up so the heads are hardly touched. Your quiver should lock the arrow shaft tightly, not the foam in the broadhead cover. That is strictly for the hunters safety. It is not and never has been meant to help hold your arrows in place. I LMAO when I hear of jokers out there complain about the heads opening in their quivers and then see how they have literally shoved them into the foam.
There now, hiss and spit away bobby, just thought I would raz a little you back this morning because it seemed like an entertaining thing to do. Have a great day!
