Hey Gang,
I'm looking to setup an arrow for an r/d longbow (66" 65#@27.5", B-50 string) and am looking for recommendations for a carbon arrow. I'd like to be able to point load it with 300-325 grains and am looking for an overall weight of approximately 650 grains. I'd also like to be able to cut them to 27.5-28". I like the idea of the thinner diameter shafts, but would like some advice. Thanks for any help gang! Matt
Beema MFX 400 should work at that length, with 300 up front. Should work out at about 660gn
Obviously YMMV depending on how close to centre your bow is cut, but it shouldn't be a million miles off (possibly a little stiff if anything)
Ooops...roughly 1/8" from center cut.
With carbons I don't worry about length,carbons do not come in as many different spines as wood or aluminum.I pick a basic static spine and trim and tune from there with the weight I want to shoot upfront.With the starting static spine you adjust the dynamic spine by shooting them and trimming until you achieve the flight you are looking for.Wanting to be able to cut them at 27.5-28 can be hit or miss.Alot depends on how your bow's shelf is cut.On bows not cut to center,carbon arrows can have the effect of bouncing off the riser instead of flexing around it.I had a used set of carbons I bought for my bow and thought I could get them tuned with more upfront weight.They got worse the more weight I added,they were bouncing off the riser on my bow not cut to center.They kept showing stiffer with the more weight added,it should have weakened the spine but it didn't.I never cut a carbon without shooting them first and don't worry about the length I end up with.That is just the nature of carbon arrows with trad bows.There is alot of used carbons for sale that were cut too short before shooting them.This has been my experience with carbon arrows on longbows,recurves cut past center are not as critical with spine as longbows can be.
AD Trad heavies.
Rob hit the nail!
I also agree with rob. Beman MFX. I use 150 up front on a total 550 grain arrow. They fly beautiful.

I really like the Carbon Express Rebels. Just the plain black/grey shafts. They are really economical and have a high grains per inch ratio. Depending on which size you get they are around 10-11 gpi. I use 100 grain brass inserts up front. I'm no carbon expert but this has been working for me and don't break the bank.
Herritage 250 will get you up there.And their tough,durable shafts.
I use Carbon Express Heritage 350's at 30" long, using a 100 gr. brass insert and 150 gr. broad-heads. I shoot a 62# recurve and my total wight is around 640 Gr.
they shoot well for me!

what Rob said , beman mfx 400's :thumbsup:
I've revamped a bit fellas. I'm considering easton axis arrows with 100 grain inserts, 125 grain adapter, and 170 grain mod grizzlies which would bring my total arrow weight to right around 650 grains along with upping my FOC(395 grains up front). What do you guys think as far as a spine for these arrows...stick with the 400 or up it to the 340? I like the idea of the small diameter arrows. Thanks fellas, Matt
with your arrow length you might be able to stay with the 400's.
Tough call I think. I'd start with the 400, but you could be at a 340. You've got the right shaft, those MFX are BAD! Hope they never stop making them!
Thanks guys! Anyone else?

With 395 up front, at your length,
definately the 400s.
As an example (I
hate doing this) I'm shooting a 57@28 Horne longbow (cut 1/16 under centre) I draw a dead 30" (63# ish) & shoot full length, 340spine MFX 400s with 350 up front. If anything these still show a little stiff. My Morrisons (same weight, same drawlength, 1/8"
past centre) shoots the same arrow perfectly.
I would suggest that by the time you've cut down the 400s (cutting carbons seems to have far greater effect than adding or reducing point weight) & poked 395gn up it's nose, you should be about spot on.
Cool, thanks Rob!
