making the change double.to single bevel

[Uncle Buck]

Do you need some serious power behind a single bevel. I am currently shooting 45#. Is that enough?

Whatever works for a dbb will work for a sbb.

Re:  Uncle Buck.  No, you do not need "serious power" for a sbb to work properly.  Actually just the opposite, if I shot forty-something pound bows, I WOULD WANT to be using sbb.  It's not the weight of the bow, it's the efficiency of your setup as a whole i.e. arrow tuning, bow tuning, FoC, broadhead sharpness, equipment reliability, etc.  dbb work just fine (obviously), they have for a  long time.  Again you have to look at everything in unison.  

Re: Kevin Dill and oldbohnter are spot on in their assessment.  Don't look to anything as being all encompassing and the end all, you will always be disappointed otherwise.  I have shot a few deer with sbb and even more with dbb, I cannot conclude which is better in every circumstance.  Having said that, I am heading down the road of committing to sbb's for a number of reasons (supported by Ashby's studies).  When the deer poop hits the fan, and I do hit bone, I guess I'd feel better knowing I shot into it with a sbb.  I have also had excellent outcomes on marginal non-bone hits with ssb's.

 As far as really big animals, Asiatic Water buffalo and Cape Buffalo etc., if you have read Dr. Ashby's studies and believe what he has published, there should be no doubt in one's mind  as to what geometry BH and bevel has a clear advantage.  Over and over again the results are very predictable.  It would stand to reason that this same information would apply to deer sized game as well, but even the good doctor does not make this claim, as he does NOT have the data to support it.  If I am incorrect on this, please let me know.    

This is not an argument, it's just a discussion of choices and options.  It's supposed to be fun and interesting.  For most of us, this is our passion, so aren't we lucky to have this forum to think about this stuff together?  How boring otherwise.

Sincerely –

Heck Amicus...I've blown THROUGH vertebrae with a FOUR BLADE more than once.

Dave Lay....my 4 blades rotate going through also.

Our "Traditional style" heads are leaps and bounds ahead of the other BH's on the market (mechanicals in particular).  A solid COC two blade (sbb or dbb), three blade or four blade is the way to go.  I doubt I will get any opposition to this statement on this forum.

Check out these DOUBLE Bevel 2 blade holes...

Well, I would hope they don't pull it.  There's nothing disrespectful being said here, and I think it's exactly the kind of talk we'd have sitting around the campfire as hunting friends...whether talking broadheads, or any other part of our experience.  As you said, Kevin, it adds a little data to our own limited experiences.  

Everybody who's really read Ashby's reports knows its not all about how many bevels your broadhead has, nor that any other of his statistical observations are claimed to be the only way to go. He's assembled some data to evaluate some of the choices we have in our hunting arrows.  It's more data and information than any of us could have done ourselves, and -truly- it is observed on animals that provide a real test for his equipment.  There's no African Buffalo season in my state, so I can't even shoot ONE!   His reports surely wouldn't have been as meaningful if he was shooting the animals we hope to every fall.  

I've taken more animals with Zwickey Deltas than any other head, and next is Magnus.   Ashby's reports didn't "condemn" heads like these.  Nor does it indicate that one has to go for small diameter shafts, high arrow mass, FOC, high MA broadheads, or any of the other criteria he evaluated.  It does give information to compare some facets of hunting arrow performance and we didn't have that before, at least not with this amount of data.   It was offered to us for free, and I think he just suggested we take from it what we will.  

Everyone on this forum is probably already way ahead of the general bow hunting community wrt the skills/knowledge that are more important than minor differences in equipment: ethics, hunting and shooting ability, limiting shot distance, broadhead sharpening skills, a quiet bow/string, odor control, etc.....all the factors that get us the right shot in the first place.  But, whether your sport is traditional bow hunting, fly-fishing, or (shudder!)golf, it's only natural to discuss your experiences and equipment choices with your friends. That's why we're here on TG, right?

Great reading here guys I don't have a problem at all with dbbs matter of face my first trad deer took a phantom to the spine pulled stropped it good as new. I really.like how tough the abowyers look. I know nothing beats placement and a field point will kill if shot is good. I hope these abowyers are as good as they look.

"Heck Amicus...I've blown THROUGH vertebrae with a FOUR BLADE more than once."

I sure would like to see a pic of that.

I think when you blow through bone it has more to do with the power behind the broadhead.

The pic I posted is typical of what a single bevel is designed to do, regardless of bow poundage. Of course within reason.

Terry, does it? its a honest question, not trying to be a smart arse, i have shot 4 and 2 blade deltas for about 30 years strayed once to sasquatches, but back on deltas, i always assumed the head stopped rotating as it struck meat, where a single bevel had more "rotation" inside the animal creating a larger wound channel. I shoot 60 lbs or so and 600 gr arrows and have few penetration issues. just trying to cut more on the way through....

[Terry Green]

Yes Dave....the entrance and exit wounds of most of my pass through kills have different angles.

Amicus, unfortunately that was back in the early 90s...back then I didn't think that sort of stuff would be that important for future reference.

If I'd have known there was going to be an 'internet'....I would have taken lots more autopsy photos for sure.
