Maybe I need to try that, lol.
2 blade broadheads do not spin.Basically because 2 blades stop spinning once they enter body, they will not penetrate as well as 3 blades and leave inferior blood trail. I'm not experience enough to argue against his points. So is he correct? Should I switch to 3 blades?
Blood trails can not be predicted by the type of broadhead, number of blades, shot placement, bow poundage, etc.This is very different than most other advices that I got. I decided to go with 2 blade Magnus stingers because of the good balance between penetrations and blood trail.
That is not correct.Ashby results are based on penitrating bone, shoulders.
Agreed, still chews my target right up but it's definitely a spiral path. Undoubtedly.Single bevel 2 blade heads do indeed spin after impact. When I pull mine out of the broadhead target if I don't spin them back through they pull out huge chunks of foam. The target wouldn't last very long at all.
This is very accurate!When Ashby was a professional guide in Africa, he became very aware that the recovery rate was directly correlated to having an exit wound. TWO holes equals a higher rate of recovery than one hole.
With that being established, when broadhead integrity is maintained, 2 blades penetrate with less force than 3 blades. It's basic physics.
So does a single bevel rotate through fecal matter?I shoot my deer when they are running away, LOL.

Good question. I'm not aware of any specifically made for smaller diameter shafts but I would think that as long as you had good, square contact to the arrow adapter and base of the broadhead it should be fine to use a regular size. The smaller shaft behind the broadhead should aid penetration as long as structural integrity remains.Does anyone make a 2 blade single bevel broadhead with a 5/16" or smaller ferrule for these small diameter carbon arrows?
A smaller shaft diameter is an advantage for penetration. It's also #5, of the "12 Arrow Penetration Factors", from the Ashby Reports.Does anyone make a 2 blade single bevel broadhead with a 5/16" or smaller ferrule for these small diameter carbon arrows?
Ashby has compared the rib of an Asian water buffalo to that of a ball joint in a whitetail. The whitetail joint is actually harder to penetrate that the buffalo rib.There's a lot of good discussion/info/advice on this thread - I applaud everyone on stating their opinions/experiences without bashing someone else...
I would like to add that while I think Ashby presents a lot of good information, if you are hunting whitetail deer, you don't need an arrow that will take down a Cape buffalo. If I was hunting larger African animals or North American game such as Elk or Moose, then penetration would be more of a consideration to me than on whitetail deer sized game and I might gravitate to a narrower 2 blade with a 3:1 type ratio for those larger animals....
While I agree a passthru is important to good blood trails, I've found the narrower 3 blade heads penetrate comparably to two blade heads on deer sized game and I usually have two holes in the deer I shoot - but maybe the arrow isn't buried 6 inches in the dirt on the other side....
It blows my mind how many compound shooters pulling 70 lbs have gravitated to 2 blade heads due to penetration concerns....In todays modern compounds pulling 70 lbs penetration would not be a consideration for my choice of broadhead design except I would stay away from a mechanical more than 2" wide.....
I think broadhead design should be geared toward the game we hunt....For smaller big game such as whitetail deer maximum damage while achieving two holes in the animal is a good strategy. If hunting larger game maybe a different broadhead that is based on maximum penetration is smart...

Well it does blow my mind based on my experiences - but to each his own. The main thing is to hunt with what you are confident with and that's what I do......It shouldn’t blow your mind.
Without too much boring detail, I’ve killed a dozen or so deer with small two blade heads over the last five years. 500ish grain arrow for most of them. I’ve had exactly 2 deer “run” at shot. One saw me prior to shot and was on alert, and died within 75 yards with crazy blood trail. The other died within 200 yards and was gut shot and was recovered a few days later due to rain storms, lack of dog, and familiarity with property(not excuses just circumstances). The rest died within earshot or eyesight, most continued the activity engaged in before being shot.
I’ve shot a half dozen or so with exodus heads. Same results mostly.
It also allows me to shoot same bow/poundage/arrow build/tune/etc. for elk and such.
Broadhead cutting width does not correlate strongly with blood trail quality. No one has tested this rigorously. But there’s plenty of anecdotal evidence to support the idea. I’m speaking specifically to the range of heads actually used 7/8”-2”. Of course if you could get a 6” blade through a deer it would stand out. This would be an easy data gather to set up. It would require honesty and participation by a lot of people though.
Hitting a deer in large diameter high pressure plumbing correlates strongly with blood trail quality. And how fast deer die. Where’s that plumbing? Neck to point of elbow horizontally speaking. You hit between the front of shoulder and point of elbow, and make two holes, you’re getting a good blood trail, and it likely means the deer is tipping over in sight.
behind that, dorsal aorta and femoral artery. Luck and only luck determines whether you hit those.
The only deer I’ve lost to a broadhead issue in 10+ years? Buck of a lifetime last year with a rage in a shoulder. 500gr arrow going 280fps. My guess is an exodus gives me 60/40 chance of getting through. Any of the small two blades I shoot 100% that deer is dead.
I’m not saying 3 blades are bad options at all. I use them too.
I’m saying it shouldn’t blow your mind that small 2 blade heads are really effective, and aren’t settled on, but actively chosen by thoughtful smart people.
