Title: Easton arrow chart accuracy
Post by: Mojostick on February 04, 2009, 06:35:00 PM
I've been using CX Heritage arrows and like them, but I don't like blowing them up while target shooting. I shoot in my basement and if you stack a nice group and a tip hits another arrow, it shatters it.

I was thinking about trying some Easton Legacy XX75's.
For my 54lb longbow, it's showing a 2020 if I used a 31" arrow and a 2018 if I used a 30" arrow.
Is this chart pretty solid?

I'm not sure I can get them from my local trad shop. If I can, I'll certainly support that store. But if I can't, is there a good online shop where I can get just a half dozen to try and get them cut with custom wraps and fletching? I'm sold on hot pink wraps and flo green cock feather and hot pink hen feathers. You can SEE that arrow.

I don't really care for those charts,there is too many variables with trad bows.Like you have a longbow,it probably won't shoot the same arrow as a recurve.Your draw length is another factor,type of string.I draw 27" and shoot 2020's out of my Fred Anderson Skookum 68#@27 and my HH Wesley 66#27.Unless you have a long draw I think 2020's might be too stiff for a 54# longbow.My 2020's with a 145 gr. point at 29" weigh around 600 grs.

Mojo,
I shoot 2018 Legacy shafts out of my recurve and longbows, all from 46 to 53 lbs, one longbow cut to center, one 1/16 from center. Each of my bows has a point weight it tunes best with, anywhere from 150 to 290gr.
I've heard/read that the charts aren't that accurate and a 2018 "should" be too stiff for my lighter bows, but they shoot well so I'll stick with them.

What is the draw weight at your draw length, and arrow length, and point weight you intend to use?

My go to bow is a Thunderstick MOAB, 54@28, I draw close to 29 and I use typically use 150gr heads.
My current arrows are 31.5" CX 150's with 150gr tips.

A 2018 cut to 30" should work really good for you.

In my experience the Easton charts are WAY OFF for traditional bows.

At a minimum I recommend going down two to three group sizes from what Easton recommends in their charts.

For example the hunting selection chart recommends group J for your bow weight with a 31" arrow & 150 grain point. Group J aluminum arrows are 2512, 2413, 2315 & 2219. All of which are WAY to stiff.

Group H aluminum arrows consist of 2215, 2314, 2117 & 2216, which I from my experience are going to be stiff also.

To complicate matters more Easton did away with the normal sizing for aluminum shafts and greatly reduced the aluminum arrow shaft sizes available. They now classify aluminum arrows shafts by spine weights i.e. 500 spine = 2117 which I haven't found to be correct.

I'd try a 2018 and go from there.

500=2016

400=2117

According to them. But, the 500s seem more like a 2018.

Easton still use's the 2018 numbering system for the Legacy's and Camo Hunters.  The New XX78 Super Slams are marked: 300 (2317), 310 (2514), 340 (2315), 360 (2413), 380 (2216), 390 (2314), 400 (2117), 420 (2312), 460 (2213), 510 (2114)

I sell shafts and arrows by the half dozen, and can build them to your spec's.

It's part of the dumbing-down of America...the No Child Left Behind Program...8^).

Actually, the Easton chart works fine as long as you read the fine print at the bottom of the page.  The Easton chart is not spined at a 26" span with a 2# weight.  You have to make the mathmatical adjustment.  Charts are, and always will be, a place to start, and they are pretty accurate when one weighs all of the information.

Spines of arrows are also altered by many variables: Centershot of the bow; type of string material; length of arrow used; weight of points; type of arrow rest/contact, and even the release dynamics of the shooter.  Use the charts for a starting point and find your arrow from there.

Go to Foxfire Archery's site. There is a great chart there, and they have taken the time to spine aluminum arrows using the same method as woodies, so they are very close.

??Foxfire Archery's site?? can't find it.

I agree with Ghostman after my recent experience -
Even though i read the spine table with bad info. (my drawlength is not the 29 i thought it was) and got 2117's, that are way too stiff for 47# at 28". Now i have 1916's ordered - still 3 groups below 'recommended' group.

Start with 2018s at about 31.5 and cut by 1/4 when tuning. (you can always recut but you cant add length)You should be close to right on at about 30". I always start long shoot a  dozen groups. Then cut and repeat. I also shoot 3 arrow groups......YMMV

Changing to aluminums to effect the cessation of Robin Hoods in the basement is an approach based on flawed logic.

Any arrows, shot at close range to a single point will hit one another and cause damage. Assuming that aluminums are less accurate than carbons, especially in close quarters, is another error.

To avoid costly repairs and replacements, either shoot fewer arrows in an end, or shoot at different spots on the target(s) with each arrow.

2018's 30" out of my Wes Wallace 51#@28" recurve bare shaft weak, but that bow is further to center than your longbow will be. I'm with Killdeer, sounds like you have it dialed in just aim at different spots!

I just picked up a doz 2016 XX75 camo hunters. My bow is 50#@28. my draw is 27.5. My arrows are 29 long. 2016's are what Rob Lee said I should use. I have been shooting cedars for the last 5 years and am switching to aluminum. I bought a couple XX78 2016's a year ago to try and they fly great. If I use the chart it has me using 2117's and 2314's. I shoot 2314's from my compound. I may fling a couple of those just to try. Am going to fletch up the 2016 camo hunters tomorrow. Tip- I but my arrow wraps from a seller on e-bay 5 doz assorted colors for $20.00. Any colors you want.

I shoot 2216 Legacy shafts 28.5" out of a 56lbs @ 27" Shrew longbow and I get good flight. Killdeer has the right idea. Just shoot a couple of arrows at a time or have different targets.

Well gentelmen and ladies I agree with the dropping down and am very suprized by all of this and find it extremely informative. Could anyone tell me why stiffer arrows show weak for me?
Title: Re: Easton arrow chart accuracy
Post by: **DONOTDELETE** on January 05, 2011, 10:56:00 AM
There is time when a stiff arrow shows weak and a weak arrow shows stiff. What is happening is it throwing the arrow off or in to more paradox.

I had arrow show Me they where stiff because I gained a few inches in draw. I put more of a bend in my bow arms elbow and they flew like darts.. So I then cut the arrow down some and shot it.

Now My arrows are 29" as where before they where 30" BOP.

Forget all the charts! Go to Stu Millers Dynamic Spine Calculator. It will get you in the ballpark and you'll learn a bunch about what changes affect the arrows spine. Pup
