The Rundown:
I shoot a 65# recurve at 30in. I bought some 2219 Easton Legacy arrows, and used 100gr field tips. They seem to be way underspined, and porpose alot.
The Question:
What spined arrows do i need? I would like to purchase more Legacys if its possible to get the correct spine.
Thanks,
Joe
Quick Correction:
The bow is 57# @ 28in, so im not exactly sure on what the poundage is when i shoot it. I have a 30in draw.
try brace height / nock point first ... i would have thought that that set up would shoot alright outta your set up / dacron string or FF ? . is your bow centre shot ?
i use to shoot a bit heavier weight but with a shorter draw outta my 'curves and used 2219 with 160 on the head .
aside from the Legacy , you can probably get more variation with some other Easton shafts XX75 etc ... a 300 spine outta the new " gamegetter " replacement all black shafts should shoot alright i'm thinking ...

You may actually be getting a false reading. Much depends on the information I don't have about your bow, as mentioned above. Assuming your bow is centershot, and plugging all known variables into Stu Miller's calculator you may be a tad stiff. Try heavier point weights up front and see what happens.
Porpoiseing is a nock point issue.Those arrows with a 125 gr head would spine 90#.You are probably pulling 63-64#.You may need something like 175 grs or more of point weight to get them close.I don't think there is any way they can be weak.
Have you shot them bare and see how the hit the target? A 2219 has a .337 spine and is a pretty stiff arrow.
My thoughts exactly JimB.
The 3 aluminum arrows I shoot the most are 2419, 2317, and 2219 at 29 1/2" and 30" draw. I too would be very surprised if you were underspined with the specs you have included.
Yup...I shoot long 2219's out of heavier bows. Personally, I'd try 2216's next...and I keep a few of different sizes available to make the process easier. Rick.
2219 are spined about 95 pounds. If anything, you have too much but that would show up as a fish tail (left-right, not up-down)
Like Rickshot said, I think 2216's are more in the ball park with a 100 grain head. JMHO
You are ceretainly not underspined with the 2219.
You are overspined with 100 grain points. Try the 2219 with 145'ish points...even 160 grain.
Thanks. Im not really into the "scientific" aspect of archery, and i have only ever shot wood shafts. Normally Ive just been able to put the arrow in the center of the target until this bow. Ill try using those 2216s on my next dozen, and just keep trying till i get it right. Thanks for all your help.
Not perfect science, But I just ran those specs you gave on Stu Millers spine calculator.
2219
I got 31.5" arrow
175 grain points
I shoot the same set up 65# 30.5 in arrows drawing 29.5 black widow bow 2219 140 grn broad head 5.5 in feathers for me just a little weak. weigh 640 or so grns ,I get much better flight out of 2317 cut same length with 175grn heads weigh 650 or so
Try raising that nocking point a little at a time and some heavier points and you should be able to make those work and fly well.They may be heavier than you had in mind but your bow should be able to handle that,easily, and if you want lighter,you could try the 2216's later.
At that weight, you could even shoot 2117, with a 125 grain point!
I shoot a 29 1/2 inch 2219 at #62 Zipper. I use 145g points 5 inch feathers and they fly well. I'd change point weight first and fool with the nocking point before I gave up on the shaft size.
