RE: Fixed or mechanical broadheads
Now, remove the broahdead and install a rubber blunt on the arrow and all of the available KE is being transfered to and absorbed by the animal with outso much as breakingtheskinand the arrow will bounce right off the animal. Yes, the available KE is transfered to the animal but what good did it do?

RE: Fixed or mechanical broadheads
Well, kind of. Actually what I do understand is that the KE of the arrow (or any other projectile) is what gets it to the target. On the other hand, it is momentum (p=mv, where p = momentum) is what drives the projectile home. While p and KE are related (they are both functions of mass and velocity) is the MOMENTUM of the arrow that drives it into the deer, allowing the broadhead to do it's work. I hear about KE all the time, and I understand the significance thereof. However, I never hear about the significance of momentum. That is unfornatute and momentum is that which causes pass through, or no pass through, bone breaking etc. Certainly penetration is not quite that simple, as many things contribute (diameter of the arrow, coefficient of friction between the shaft and the target, and all that stuff), but again, all things being equal, it is momentum that is the real deal behind penetration. Momentum = penetration, penetration = dead critter. Velocity is important is more important in getting the projectile to the target, but mass is equaly important when it comes to penetration...

You need to take some more physics classes because a broadhead tipped arrow is not designed to transfer energy to the animal at all. It is disigned to pass through the amimal and cut as much tissue with as little resistance as possible on its way through. It does not kill by the transfer of energy it kills by hemmoraging. The more tissue cut then the more hemmoraging occurs. If the arrow stays in the animal then it blocks the flow of blood rom the wound to the ground and can make finding that animal more dificult.
You want all the KE to transfer to your target thus giveing a more effective and humane kill.

Which is EXACTLY why I like a 3 blade mech. w/ a 2" cutting diameter. Or is my thinking just completely wrong here??

Someof the reasons I don't like mechanicals is becausethey are pain to practise with. I also don't like the way they can catch some thing on the way to a target, or the way they fit in a quiver.

Just shoot a Muzzy like everyone else! (Ha! Ha!) I am faced with a serious delimma myself..... Just started an Archery-Only hunting ranch. Do I allow hunters on my ranch to use mechanicals????? Would you????? If YOUR livelihood depended on it, would you still prefer mechanicals? Better give this some thought.......

RE: Fixed or mechanical broadheads
For deer hunting, I wouldn't flinch over someone using a mechanical. Particularly the ones that open before going through the hide - like the Rage and the Rocky Mountain Sniper. But for bigger game, and especially for bows that are pulling a little on the light side, I would want my clients shootingfixed heads.
