Dave, "The Ashby reports again"? Are you serious? This man is by all accounts the leading authority on archery ballistics. I also read a lot and have never heard anyone discount his findings or question his qualifications.

"A guy had brand new Rage 2's with no blood trail." -Which means that one or more of the factors I originally posted were missing. Either poor shot placement, no exit wound or my guess is that the "new" blades were not all that sharp. Just because broadhead manufacturers claim that thier blades are shaving sharp and ready to hunt with right out of the box dosen't mean that it'salways true. I have seen many brand new replacement blades that were duller than my old ones.

I shoot 2 blades with no bleeder. SteelForce, Muzzy Phantom, Magnus. I used to shoot 4 blade repacement blade heads like Rocky Mountain and Wasp but would only put 2 of the 4 blades in. They all group together and while I'm not a great target archer, I do have to shoot each arrow at a different bullseye to prevent cutting off feathers and knocks or damaging one broadhead with another.(in the target). I also don't shoot over forty yards.

You are right that with broadside shots on deer sized game penitration is rarely an issue. It's with close range treestand shots orquartering shots, orwhen bones are hitthat the penitration issue comes into play.

The unequalled penitration of a two blade head has been proven beyond argumentand has been cited by more than just Dr Ashby. By design a two blade head only has to break a bone once to penitrate it, whereas a three blade has to break the bone in at least two directions to penitrate through the bone and reach the vitals. Breaking a bone once requires less KE than breaking the same bone twice. While any broadhead will blow right through a deer when no bone is encountered, in the area of the vitals there are bones. Most of us hunt from treestands and penitration is also amajor concern with steep "top down" shots toachieve a pass through which will greatly improve the bloodtrail.



MDbuckhunter, I admit that my claim of superior flight characteristics is based largely on personal experiance. Regardless of the bow I am shooting, 2 blade heads invariably produce much tighter groups for me than muti-blade heads. That said there is some science to support my maddness. More blades means more surface area and a greater likelyhood of air/wind resistance effecting the flight of the arrow. Greater surface area also impeads penitration by creating more drag.

Sorry guys, didn't mean to ruffle anyones feathers -Sharps
