R U spined correctly - I can check it for you.

[bmac]

draw length = 27"
poundage = 65#
one cam or two = 1 cam
hard, medium, or soft cam = ?, maybe medium
axle to axle length = 32.5"
brace height = 7.5"
type of arrow = Easton ST Epic
arrow spine = 340
arrow length = 27 7/8
number of vanes = 3
length of vanes = 2" blazers
tip weight = 100 gr

Thanks

Mine is an alleigence
29" dl
70 lb
33&5/8 ata
7" brace height
gold tip xt hunter 7595
28&1/2" (shaft length)
340 spine (I think)
3 vanes 4" long
100 grain heads

THANKS!!!

Firetx,
I assumed 2 hard cams. If so then you are spined about right. You could soften up a little by going to a 125 grain tip. Speed exceeding 275 and 73 KE. If you are 2 medium cams then calcs show a little stiff. Going to the 5575 shows to be better spined. Anyone know what cams are typically, hard, medium, or soft?

Thanks! I don't know about the cams. They are supposed to be speed cams.

heres mine

Switchback XT 62 pounds, 31 a/a, and 27 inch draw
Goldtip XT hunter arrows 5575, 400 spine cut to 26 inch arrows, 3 blazer vanes (2' vanes)
100 grain slick tricks, also has wraps on arrows.

OK Drenalin, here goes, but just so you know my daughter's a senior at UT so I get one aggie joke. According to your posting you are shooting 2 foot vanes.

According to the calcs you are off the chart stiff. FYI, I used 7.5 brache height and 1 medium cam. Is the arrow length right, excluding tip and nock. Sounds a little short. Learned to watch for that from Sharkhunter's wife.

I think speed cams mean harder cams so maybe the hard cam calc is correct. Here's to shooting groups you can cover with a moonpie.

Use the Carbon Express Cheetahs if you can, they have the lightest GPI that I have found, if not, use something like the Gold Tips or Easton Axis. As for tips, start at 100 and go to 85 if you have to.

For the heavies, use the Carbon Express Rhinos or the FMJ Dangerous Game with 2 and 4" vanes and 210 tips.

Thanks man! I appreciate it.

Mountainman,
checking the light arrow first using a Carbontech Cheetah 3D 400 with an 85grain tip and assuming 2 med cams. The cams hardness makes a big difference. You would be a little overspined with speed approaching 280. Go with a 125 g tip and speed drops off to a little under 270 but calcs show the arrow to be better spined.

I'm an FMJ fan so I used the FMJ DGs with a 300 spine. I assumed 2 medium hardness cams. If that's right then they're a little overspined. If you have 2 hard cams then you are spined very well. I have to find out more about cam hardness. It makes a big difference. Good luick on the big game. PS: speed was about 200 with 65 KE

[TX kyleboy]

what poundage do we need to shoot to make us both in spine???

Yours specs out at 76 and Mrs Sharkhunter at 68. I'm being meticulous and trying to get all these numbers entered correctly so I say this feeling pretty sure about good data entry.

sent you a pm with the link for the pdf. converter. hope it works for you

DL=30
lb=70
cam=1
ATA=29.75(DXT)
Brace=7
Arrow= Beman ics hunters
spine=400
Arrow length=29
vanes=3
vane length=2"
tip weight=100

Mine’s probably way off, never really put much thought into it.
Thanks.

Not so Green Arrow. Software shows you are spined almost perfectly. And blazing fast at almost 300 fps. I used 1 med cam. If I change to 1 hard cam you are still spined very, very well.

BMAC,
calcs show overspined. You would be better spined with a 400 spine arrow and 125 grain tips. Check with your local pro.

klooney,
the cam hardness will make a little difference for you. If you have a hard cam then you are spined well. If a medium cam then you are a little over spined. According to the software if you crank it up to 68 and go with a 125 g tip then you are spined about perfect.

OK, been at this for three hours. I'm hungry. Signing off for a bit but I'll check back in and do some more of these. I like learning and hopefully helping a little too. Thanks for the PM wassaw. I'll try to teach myself some computer skills, too. After I eat something. If you TBHers don't here back from me then come check on me because it's probably because I passed out before I made it to the kitchen.

[Green Arrow]

Sweet
Thanks TX kyleboy.
Ive just shot what felt and flew right i guess.
