Arrow Help

[Little John]

With a 30" draw you are going to have a hard time getting perfect broadhead flight out of 2 bows that are 10# different in draw weight with the same arrow.
I would shoot 2 different arrows, or put both bows at 60#
I shoot Gold Tip Pro hunters. The are the straightest shafts I've found for the money in my opinion.

at 30 in you need a 31 in arrow, from either bow the 300 spine is the arrow.. so yes you can use one arrow.......

Why would you need a 31" arrow at a 30" draw??  I have always shot the same arrow length at my draw or an inch shorter than my draw length...

 I agree with littlejohn on this one... You pretty much need 2 different arrows at that much of an increment on your draw weight...  At 60 lbs with a 30" arrow you should shoot a 340 spine, and at 70lbs with a 30" arrow you should shoot a 300 spine...  The 340 spine will carry you to about 66 lbs at a 30" shaft... So a little food for thought if you wanted to shoot both bows say at 65 lbs (which is more than enough at that draw length with todays technology) you could shoot one arrow...  A 340 spine at a 30" shaft length...

I have always used a arrow one inch longer then the draw length..  as does the shop down here.. and your right from 59-63 with a 125 the 340 will be fine at 30 in.... but from 64-up the 300 would be the arrow to go with.. so if both bows were set at 65+ the 300 would work for either at 30 or 31 in

I wouldn't shoot a 125 in my opinion... And all of this is strictly my opininon as there are 5 million different ways to set up a bow these days and 5 million different products one can choose from...  I was basing my spine off of a 100 gr field tip as that's what most people shoot now a days.  I just don't like arrows longer than the draw length itself as if it matches the draw lenght is should match the front of the riser not counting your tip...  When arrows are longer than the draw lenght it 1) add extra weight for no reason and 2) looks dumb with all that shaft hangin out there!!    I know this is all about looks right...    This is just my    on this subject...   

Here is my arrow set up...  Easton FMJ 400 spine at 27" with an 85 gr montec and blazer vanes with a 4" wrap...  The finished weight is 407 grs and I shoot them out of a 27.5" draw at 66 lbs and they are darts!

Ya I see where your goin for sure, also this guys said he was using a 125gr head.. I use a 100 myself.... another question would be is the 60lb bow a 50-60 or 60-70 because that would change the arrows as well.. at 30 in at 60 max the 340 is the arrow.. but if its a 60-70 then I think the 300 would be better because it will work with both bows     I shoot a 340 at 28.5 in with a muzzy mx4 with a wrap and 2 in blazers.. at 68 lbs.. they also fly like darts

I've seen allot of set-ups at 70# and 30" and i've never seen anyone shoot a 300 spine?
We don't even have a 300 shaft in the shop. And i've never special ordered ant to my recollection.
And almost everyone I set up has an inch shorter arrow than there draw, or an arrow matching there draw.
I'm a 30" and shoot a 29" arrow and still have the recommended inch and a half past the fall-a-way rest
I'm shooting 400 shaft at 65#. Like 288 said its an opinion.

[Hoytstaffshooter83]

it is and there is always standards people should go buy, like the easton book for example.. if you look at that chart... most anyone shooting over 63 lbs with a 100+ grain tip and 29 or over should shoot a 300

[archery288]

Which cam chart are you looking at??  If you use the shaft selector online with a "single or hard cam" as that's what a Mathews is and select a 100 gr tip and a 30" shaft it puts it in at a 340 spine...  Not trying to get in an arguement here I am just tryin to get the man the arrow that is going to work for him!     We still don't know if he is wanting to shoot one bow at 60 and one at 70 then all this is off...

Sorry guys, gone for a few days.  My DXT is 60 lbs and I really like it for my heavy cover, short range shots.  It kind of sounds as if I will need two buy two different arrow set ups.  I own and have shot both 100 and 125 broad heads.  I used to only shoot 100's but last year I experimented and found that the 125 flight was far better with my set up.  I don't know why, other than my set up liked it better.  I currently shoot 29.5 inch goldtip 5575 and according to their chart that arrow fit both my bows and both 100 and 125 broadheads would work.  I Just don't like the gold tips at ranges much over 40 yards thus why I am changing arrows.

Thanks for all the help and keep suggestions coming.

Ok well at this point you will need 2 different shafts...  At a shaft lenght of 29.5" with a 125 gr head you will want a 340 spine for the 60 lb bow, and a 300 spine for the 70 lb bow... 

[Hoytstaffshooter83]

yesn that is the chart.. I was using 125gr heads as that is what was said he wants to use, but with the new info yes a 340 and 300 are what is needed

I would disagree with this for the most part, I shoot the 340 Full Metal Jackets at 28" exclusively with 100 gr. Broadheads. I shoot a 55-70 Martin Slayer Extreme. It does not make any difference whether I am on the low end or high end, my bow will not shoot anything but 340s and stay consistant. I have tested the 300s and 400s and found erratic flight with them. Unless 29.5 make a difference, I would not think 2 shafts is necessary.

The extra inch and a half of shaft lenght makes a world of difference and so does the tip weight...  Two different shafts would be recommended for this situation.  There are various arrow combinations that can work effectively and the shorter the shaft the stiffer it becomes and the lighter the tip weight the stiffer it becomes as well... Not trying to start an arguement, but in his situation it would be recommended he buy two different shafts..

Thanks Everyone.  Really appreciate the insite.
