My goal is to fine one arrow (with differnet broadheads) that will shoot out of my 55 lb recurve and my 53 lb Omega longbow. That turns out to be a full length 300 axis on stu millers calc. All of my arrows to this point tuned to any where from 29-30 inches. I shoot the recurve on an elevated rest and the longbow off the shelf. Is this a viable option for my two set ups?

I would think a 400 Axis would be fit both bows. I shoot 52 pound Pronghorn longbow my arrow are  Axis 500 at 29 inches with 75 gr brass insert and 165 gr broadhead.

Sounds pretty stiff to me I shoot 250 up front with .400 spine 30.5" and they baresfaft perfect out of a 50 pound acs and 52 tall tines

I can't get 400s to work in the calculator. I think the  SDB string my be the cause. I can get 340s to work, how do you guys get such heavy broadheads to work on a 400 spine arrow?

 God bless.

I would think 400's would be the best option.. the thick wall of the axis will tend me show stiffer than other 400's in my opinion.

Sounds stiff but who knows, give it a shot. I thought Stu's calculator recommended arrows that would be waay to stiff for my set up but they turned out to be pretty close to right on.

You ought to try some of the Arrow Dynamics shafts.  I can shoot the AD Trads out of my 50lb longbow and the 60lb one as well.  Very forgiving shaft.

I have to shoot around 10lbs lighter arrows according to Stu's calculator. I think it has something to do with my release.LCH

I shoot 400 spine out of my 57# TT, 100 gr brass insert 175 gr field point. I think 300 will be too stiff, but who knows? The Axis are great arrows however!

Don't get too caught up on what the calculator is telling you.  It's a great tool but use it to get close then let your bows tell you what they like.  I would recommend buying a test kit with different spined shafts and a set of different weight field tips to find out what works best out of your bows.

Who cares if they work in a calculator. Just shootem they will work

I shoot 400 axis with 100 grain insert and 150 BH out of my 54# pronghorn and #51 yellowstone, both 3 pc longbows.

i shoot 400's with 250gr point and 100gr insert with 2 1/2" 2020 footing out of my 57#@28" recurve drawn to 26" and the arrow is 30 1/4" long. work that out.
alot of people said that 340's should be good but i had a hunch that they would be too stiff. listen to the bow.

everyone of my setups i that know is tuned that i have entered into the calculator is apparently vastly underspined.

Way too stiff bud!  I know "what works for some, may not work for others"..but..unless you plan on hanging about 4-500grs. on the end, there's not way they will be your best option.

With enough fletch, you may get them to fly "ok", but it will just be covering up the problem.

Depending how much pt. weight you plan to use,a .400 or at most a .340 would be a much better option.

400's would be my advice too.  I used 29" 400's with 200 grain points out of my 58# Super Shrew Samurai longbow.  I use 600's out of my 44#@28" Super Shrew Classic Hunter, 29" BOP and 220 grains of point and insert wieght. Stu would have me in a 400 for that bow.

I shoot the axis 400 out of my bows from 45-57lbs. I use a 75gr insert and 100 grains up front. I shoot full length arrows and use a 5" shield fletch. Get excellent flight and good penetration.

Don't underestimate the affects that the shelf cut (comparison to center), and string size (strand count) can have on spine selection for a particular bow.

I use FMJ's in 400 spine cut down to 28.5", with a 175 grain head on my 53# Eaglewing Tallon II.  I draw 27.75-28" even, so the poundage is right on.  The bow is cut -3/16 past center and I use a 8 strand SBD string.  This arrow was the result of bare shaft tuning.  If I had a 16 strand string, I'm betting I'd be using a 500 spine arrow.  

String size can play a HUGE role in spine selection, do not underestimate it.  A lot of guys would say that a 400 cut down to 28.5 inches would be too stiff for my set-up, but it's actually right on.  And, in actuality, the shaft shows to be on the side of more weak then it is stiff for my setup when bareshafting, just barely.

Thanks for all the advice. I think the string having a major influence on my arrow spine. I'm still going to play a little with some bare shafts to validate my theory but I think Pitt987 is correct.

Hi guys! I have a dz of Easton Axis arrows spine 400, 31" and 3 5"right wing fletching, my draw length is 29"!   I plan  to shoot them on my BlackHawk Bows straigth reflex longbow 64" #61@28", HIT brass inserts 50-75 gr and 125-150 gr points ,but one of my friend sent me a mail :
 The Easton chart you are using will work well for Recurve bows but not for longbows or self bows , the arrow needs to bend more to go around the non center cut shelf and then recover.  
           
           
             

 Is it shootable on my longbow ?I have a vintage Bear Grizzly recurve 62" #50@28" too,but i shoot 30" Axis 400 arrows! Thanks !
