I shot a 30lb bow and bought a bunch of arrows to match that bow but its been over 2 yrs ago....Now, I need to get the right spine before I order some shafts....Thanks for your help on this.....

I'm shooting 1716 Platinum Plus, full length, with bullet points (65 grains?). My Bow draw weight is just over 30 pounds on the fingers. Bow is set up with a wire rest and plunger button. Shot 1816 too, but the 1716 seem to fly and group a little better. This is strictly a target setup, so if you're looking for a hunting arrow, I would go a little stiffer with more weight in the tip.

You'll probably need .800's but not enough info to say for sure. Draw length and center cut of the bow will make a big difference.


Oh and btw, to the fellow shooting .400's out of a 35# bow.... your arrows are waaaaaay too stiff.

At your DL, Brian is correct, 1716s @ 880.
Not sure where he got that idea from though. ( Hi Brian)

Dave, didn't we go over this a few years back??? ;)

I'm only a newb but I have been shooting 600's on 30" carbon to carbon arrows and 30# recurve. But I think they might be too strong. I'm probably going to try 700's next time.

24# limbs call for a 1616 @ about a 1000 spine.
If you want arrows for both the 24# and 30# limbs, stay with the 1716s.

The years go by fast when you're having fun, don't they?

John Champion is making my some arrows today (700s) for the ILF rig....He told me today he would order me some shafts for the 24lb bow.....I have a 29 and half DL so that will add 2lbs on the 24, so 26 might allow for a stronger spine, would it not?

Ah, no.

Depending on the type of limb and bolt position, a 24# bow gains about 1.2# and a 30# bow gains about 1.5# / inch.
Yes, the initial weight will be higher is you crank the bolts full in.

A 29" 700 with std weight head spines to about 35-40# +/-.

For what you're doing, they are probably fine, but why not just get the right arrow in the first place.

I did get 6 for the 30lb bow which I think will work....they are 600s with 125 up front.....I’ve got the 900s for the 24lb limbs to try out.....

Enjoy your bow. If you have gold tip inserts you can add wts to the tip if you need them. But bet the arrows will fly fine, some people likem a bit stiff anyway. I've shot 500s with 145grs on a 34# bot and they worked fine- I did have a plunger tho.

First thing to do is make sure your Black Hunter is what it’s marked. I own 3 and none are actually what they are marked at. My 30# BH is 33#@ 28” so around 31@ my 27” DL.
My first 35# BH was 34#@28” so around 32/33# @ 27”. And my newest BH was a 35# that comes in @ 38# @28”...36.5# @ my 27”DL. All of these bows shoot a 700 spine arrow 30” long 25 gr. outserts w/ 85-100gr. TopHat field points like darts. This is what I am shooting in 3D.
