What size carbon arrow for 30# @ 25" draw? Thanks for the help, David

700 possibly 800

Depends very heavily on the bow itself and on the length of the arrow.

I have an ambidextrous longbow with #29 limbs for loaning out to my sons’ friends to get them some exposure, and one of the guys here whose judgment I take quite seriously recommended that I get some 1400s for it. Hard part is that my boys are drawing bows marked from #40 to #55, and it’s tough to negotiate lower poundage with guys from 17-20+… ;)

#30 is a lot more sane as a starting point!

How long do you want the arrows to be when completed?

800"s

1200 or 1400 left overlong would probably be best, but there is tolerance that can be tuned for by other means. The Corax bows will need different arrows. 500, maybe 600.

But we are all just guessing. You need to buy some test arrows to find out.

The most versitile in my experience is 600s left full length, so I generally tend that way. - lbg

.800 or .1000 if you want to keep the point weight, and thus trajectory reasonable.

My daughter shoots 1000 spine Easton from her 30# bow at 25” with shelf cut 3/16 past center with 28” shafts, 100 grain up front.

I'd go 800 max. 900 would be closer to it.

Many years ago I made a few dozen wood shafts for my wife #25@28" recurve. She draw 25" so about ~20#. I just checked her shafts on my ACE spiner. 26-26.5" shafts 100 grain points spine about 20-22# or .900 series shafts. I can actually get pretty straight flight from some of them if I short draw them with my #30 recurve. Anyway there you go good luck.

I shoot 800's out of my 32# Bear C-mag. They are cut 28-1/2 inches and 100 gr points. I would think you would need 900 to 1000 spine.

Thanks everyone for all the advice, David

i shoot 900s out of a 30# at 26.5"

Any spine works for beginners.. they don't know the differnce. However the small diameter arrows like 1200 and 1400 are light enough to cast well and the tiny diameter moves them closer to the shelf. BigJim

I’d go 700 with 175-250 of tip weight. My 37lb Pika loves 600 axis with 250 up front.

Dicky, surely you jest.. That would produce roughly a 15-18 grain per lb arrow for a 30 lb bow! He might as well just throw the arrow.. BigJim

Your right Big Jim I think I could throw it faster than the bow could shoot it

What bow model is it? Longbow or Recurve? Is the bow cut pat center, to center or off center? How much past or off center is easily measured by taping a thread in the center of the limb bolts or on the limbs over the riser. Keep it tight. Then measure distance from thread to the arrow strike plate where arrow would contact.

I guess my mind goes right to hunting arrow. I don’t think there’d be anything wrong with shooting a 400gn arrow from a 30lb bow. Especially a modern type recurve. Usually right around 7gpi for a 700 spine x28” long with a 175 would put him high 300’s. But sure, 3D shoot a 800 or 900 with 125 would be fine .

Def no stiffer than 800’s. Im betting 1200 spine would work. Big Jim sells them cheap

I can shoot either 950 or 1100 out of my 32 pound target bow with 27" arrows. You are looking a bit lighter and shorter- suggest something around 1100 or lighter if you have a center cut bow and light points.
