Going Heavy - Ashby

[Intruder]

I'm looking for input from those of you who have experience using the concepts/methods of Dr. Ashby.  First, let me say that I am not looking to start a debate or looking for reasons not to adopt Dr. Ashby's methods.  What I am looking for is recommendations or tips regarding a setup for the parameters I'm outlining below:
1. Compound bow (Hoyt AlphaMax)
2. Shaft length 28.5" (excluding broadhead & nock)
3. Achieve a FOC of 20% or >
4. Abowyer Wapiti 175 Grain Single Bevel Broad Head
5. Total arrow weight (broadhead/inserts/shaft/etc) of > = 600grns

Any info regarding shaft selection, tuning, fletching, inserts, even alternate broadheads would be appreciated.

Todd_ID is your guy here...he's used these methods and is fluent. You might try a search on here for more info because I know he had a thread on here at one time. If he is at work, it may be a few days before he sees this.

Intruder,
My  . 1. I also have a Alpha Max. Jury is still out on how much i like it. The cams are fairly radical which causes the arrow to jump up at the end of the draw. Still can't get it to shoot as well s my other Hoyt. My arrows are cut to the length that allows a broad head to clear my rest. You can have the broad head in front of or behind the front of the riser depending on your rest. You never mentioned arrow spline. With that heavy broad head make sure that you match you arrow spline to match the bow draw weight. With the wrong spline, you will never be able to get your arrows to shoot good groups expecially with broad heads. I have no experence with the Abowyer Wapiti broadhead. The important thing with shooting a accurate broad head is a well tuned bow. Your on the right track with determining FOC, but make sure you make sure that the arrow spline is correct and the bow is tuned correctly. I guess that your not looking for arrow speed as much as down range energy with a 600 gr arrow.

Scroll down, there's lots of studies posted here from Dr. Ashby. I'm guessing Intruder's already seen this but for those who haven't...

Wow - Very interesting level of detail and testing, but expensive .  $109 for a three pack of the Ashby single bevel?

New laptop... still working today on getting On Target back up and running.  I can say that it's possible to shoot lengthwise through a big bodied muley buck with it.  Shattered front shoulder and femur both.

There's plenty of good broadheads though that fit the requirements.  Mine are Grizzly heads at like $23 per 6.

My arrow is an eston axis .300 cut to 29" 3 blazers and a wrap 100gr muzzy hit insert 125gr magnus stinger. Total weight is 575gr. I have a hard time believing anything in this state would stop it. I shoot a maxxis 35 at 70lbs and it shoots 250fps with this arrow. if that's what your looking for but hope it helps. Oh yea, 18% foc

How much does the arrow weigh?

[RadSav]

I'm not a real big fan of the dentist.  He puts so much emphasis on penetration he usually forgets what gets the job done - sharpness.  To your question though - I can not give you a recommendation on shafts without knowing your draw length and weight.  However, downloading "Archers Advantage" will go a long way to putting you on the right track.  With that heavy an arrow/broadhead combination you are going to need some good size fletching or four fletch.  Plastic or naturals shouldn't matter much with that kind of FOC combined with the modern risered bow.  Muzzy makes a good assortment of brass inserts for most of the carbon arrow sizes out there.  For the price of just a few of those broadheads you can have a local Swiss Machine shop make them for you.  I've had Moonlight in Monroe and Foulger Precision in Castle Rock do good work at good prices.  That would allow you to use what ever broadhead you wanted and fall into your FOC requirements.  Good Luck!

I find that if the arrow is built properly you don't have to have huge fletchings. I have some 700 grain arrows, 17% FOC, fletched with three 4" feathers and they fly well. If you built them to fly straight without any fletching whatsoever you can get away with smaller fletching.

It has been awhile RadSav since I read all the studies but I seem to recall that Ashby puts quite a bit of emphasis on the quality of the steel; that it has to be good enough that the broadhead will still have a sharp edge after breaching bone. But yes, his studies are focused on testing a given arrow's ability to deliver the broadhead to points beyond the near side rib.

Grizzly good heads. Takes awhile to get the hang of sharpening them
