First let’s not get nasty! There’s been a lot of that lately. Do you think this arrow would be stiff, gold tip 500 cut to 27” with 250 up front with 3 5” feathers. Bow is rd cut to center lb 40@26. Thanks

JMO, I would go lighter in both spine and overall weight.

I cut my 500s to 27” and add an RPS insert to the front with a 1.5” footing of 2117. That and 200 gr points work for me at #52. But that’s with a not-so-aggressive LB that’s not cut quite to center.

So… it depends.

If you're drawing 26 inches, then yes, it's likely to be on the stiff side. Only way you'll know for sure is to try it.

yes

yes

There you’ve heard it.

What about 600 spine at that length and 250 up front?

That’s still going to be a hefty arrow… 11 and change, right?

I got my 16-year-old a #40 and I’m thinking 700s with 125-150 up front.

Most of my arrows are pretty generously fletched, so he can shoot 500s (+200) and 600s (+175) pretty accurately, but he’s still dealing with the trajectory.

This is a 16-arrow group from about 25-30 yards. About 2 feet wide, tops…. But those heavy arrows are tough to hit with….

.600 will be closer but that's an awful lot of weight.

And just an fyi...the fact the bow is cut to center is meaningless unless you are shooting it with a bare sight window. The meaningful measurement is the one taken after it is set up to shoot.

Arrow weight? Its 426 which is 10.6 gpp

Thats gt warrior shafts. Yes gt trads would be heavy 485

Too stiff, 600 spine at that length/ point weight.

One way to think about this is, cutting off an inch of arrow length from 28 to 27 would take the spine down over half, from .500 to about 450, so it's not the same arrow. Adding the 200 grains just takes it back to close 500 again, but it's still an inch shorter so the weight on the tip doesn't displace much spine.

So then we can say you're shooting a 27" arrow, from 40#@26" draw, so yeah....it's still 500 and it's still too stiff. You may hit just fine with it, but it's not flying well enough to use as a hunting arrow in my opinion, as any anomaly in the flight will take away any advantage of the added weight....if any is there to begin with. Wobbly arrows lose effectiveness quickly.

You're in 700 territory to be brutally honest, or a 600 left at about 29" with about 250 or so out front. And that's assuming you mean 40# at 26" and not a 40 pound bow drawn to 26"...big difference there.

You be thinking of buying the arrows from some one. Not sure,but my 500 spine arrows are full length with 150 gr. heads, and they will bare shaft tune with some light poundage bows that I own with no problems. lots of variables.

For me it would be a shade stiff.

Yes

“ but my 500 spine arrows are full length …”

Apples and hedgehogs.

You really have to decide what it is that you’re going to tune around. Is it desired arrow length, or is it a GPP/All-Up weight target??

You can GET TO the weight you want AND the length, too, of course… But you really have to start with one or the other. Which means you have to start with your actual net draw weight and some sense of how close to (or how far past) center your riser is cut.

I get the feeling that a lot of people are starting with whatever shaft they have lying around and punting from there…..

Cut and shoot your arrows 1/4” at a time,you may get by with 30” or 31” 500’s with the point weight you want.

Took me a long time to come to this realization because I am stubborn and ignorant. Cutting an inch off an aluminum changes spine fairly little. Cutting an inch off carbon changes spine A LOT! To shoot carbons out of 40# / 27" for me I had to drop all the way to 700 spine.

Longshot what tip weight?

With my 58” Big Jim D/R “ThunderChild” 43#@27” D97 skinny string = 30” GT Traditional 600 shafts with GT nock 7” vinyl wrap 3 5” feathers the factory aluminum insert and 225grn screw in FP’s or Broadhead’s,tunes perfect for my style of shooting spit finger with this D/R longbow.

shoot it full linth n see how it flys. 500 is pretty stiff for trade bows imo.

I'm shooting similar specs. I ended with 600 spine and 275 up front.

I ve been very busy but I have gotten back to this. I may have found my arrow. I ve been bare shafting Gold Tip Warrior 700 spine shafts. They are cut 27” with a 100 grain brass insert and 150 head. They have been flying nice. I then fletched that arrow with a 7” wrap and 3 5” parabolic feathers and gold tip nock. Seems good so far. Anybody surprised by this or do you think this sounds right? Bow is cut to center and is 40@26

It doesn’t sound entirely crazy, but I am very curious as to what your all-up arrow weight is at this point?

I guess I’m saying that I’m not sure that the brass insert is necessary, but it really does come down to what you like and what works for you…

420. That’s 10.5 gpp

No opinions ? On this site lol

If it works it works. None of us can see you shoot and we have no real idea of what you will or won't accept.

It sounds at least ballpark to me . You know best good luck

Way too stiff

Mechanic why would you say that when earlier you said 600 would be good?

I think it would be too stiff cut at 27" based on my experience with 500 carbons. It doesn't take much trimming on a carbon to make a big difference in spine based on my experience. As mentioned above, you'd get away with cutting more with 500 spine aluminums (2016's).

I also think you'll probably still get good arrow flight with the 250 up front and the 3X5" feathers.

There are a lot of guys here with WAY more experience than me with arrow materials and dynamics but these are my opinions.

If you're happy with it and they are shooting good for you then that is all that matters IMO. Good luck and have fun!

600's

Yup

Kanati I said 500 too stiff. 600 is better choice at that length/ point weight. Original comment- Too stiff, 600 spine at that length/ point weight.

A .700 spine carbon is the static spine equivalent of a 45'ish pound wooden arrow. Cut down to 27" that brings the spine up to ABOUT 50lbs.

Hang 250grs. on the front like the OP said he did and you break the dynamic spine back down to 45'ish pounds. Every bow will shoot a range of spines and the closer to or further past center the bow is set up the wider that range becomes.

Not surprising at all that it shoots well.

Thanks Frank they do shoot nice. I will post a pic next time i shoot. Skeeters make it hard to shoot lol!

Yes

Yes, way to stiff.

Yes the 500. Read further i now am shooting 700.

I shoot a Yellowstone Hunter 45#@28” rd longbow and I draw right at 28” I shoot a 600 Easton which is 7.5 grains per inch cut 29” with factory inserts with 200 grain head. Puts me at 456 grains.

The carbon arrow issue makes me dizzy ??. I shoot a Yellowstone Half Breed that is 62" and 41 lbs@ 28" and I draw 28. I'm shooting Carbon Express 600s at 28 1/2" with a 125 grain point and get perfect flight. I shoot the same arrow out of a 66" and 40lb@ 28" Horne Combo Hunter with longbow lbs and get perfect flight. So many variables.

I use about that arrow setup on my ~52-53 lb bows. So I would guess stiff.
