Am I the only one who shoots underspined arrows better?

[shortstroke 91]

Let me start with specs, I shoot a #46 @ 29" Kanati with a 12 strand B-50 string and 3 under. I get the best flight with full length GT 35/55 and 250 grain heads and also 11/32 #50 32" cedars with 190 grain heads. If I use Stu's charts I'm way underspined but these set ups fly great both with broadheads and bareshafts, and hit where I'm looking. I've been told with my set up I should be shooting near #65 woodies but they all hit way left (right handed) to where I'm aiming. Am I an exception to the norm or are there others out there like me?

I think a lot of people shoot weak shafts better. With a finger release the arrow paradox is accentuated, and an arrow that flexes easier is more forgiving to a finger release.

[OBXarcher]

Nope you are not alone. I shoot basically the same arrow from my bows and they range from 48-53 # @ 28

By the calc I am 15# under spined. They fly great with broad heads.

My best shooting arrows are 55-60 cedar 29" with a 125 snuffer and 125 woodyweights from a 63# longbow

I guess the ultimate test would be do they result in game being brought to the freezer? If so, then I would say don't worry about it.

If it bare shafts right and shoots well I don't think it is week. Sound like it is about right.

I shot a Kanati 46@28 with 29+ draw the other day. Shot my 31" 5575 with 275 up front close to tuned. That was with 8 strand FF sting and no silences.  About 18# under spine per calculator if I got the center cut right.  

You have a B50 string and probably silencers. that will reduce performance some.  GT 3555's are only 30" full length. I am not that surprised it shoots well for you.

The popular opinion 20 years ago was to shoot arrows spined 10-15lbs heavier than the bows draw wt. Then you were to add another 5lbs of spine for broadheads. It messed me up for years. I didn't know better and assumed arrows kicked their way to the mark.

On the advice of a friend I tried arrows matched to the bow wt for a recurve and one spine group lower for a longbow. Man what a difference! I've been following that advice ever since.

This is my rule of thumb for wood. I just follow the Easton chart for aluminum. Works for me.

Just my observation.......sloppy release needs heavier spine, clean release needs lighter spine.

[Friend]

Not statistically substantiated, but this has been the observations from my limited experience.

On several different bows using the same shaft with minor modifications to length and major modifications to the end wt.

Great flight was attained at:
1. Stu's calc recommendation
2. Arrow set-up was ~15#'s underspined
3. Arrow set-up was ~30#'s underspined.

I shoot full length 2016 with 145. Grain heads out of my Kodiak hunters, one is 43 pounds the other is 47 both at my 30" draw. Underspined according to Stu but work great for me.

[Manitoba Stickflinger]

Me too! I can shoot a 500 spine arrow out of almost any weight bow with great flight....with 200 grains plus insert up front! Any time I've had buddies with tuning problems a weaker arrow worked to fix it. I think a common problem is starting with a shaft too stiff. JMO!

[Son of Texas]

I've wonder the same thing, I shoot a 48@ 28 Kanati 8 strand FF with 35/55 GT full lengh with 300grs up front.I've bare shaft tuned and that is what it takes to get it tuned.

[Night Wing]

I think it depends on how close to center or past center a bow's shelf is cut along with the thickness of the side strike plate.

With that said, my Blacktails are cut 3/16" past center and my side strike plate is 1/8" thick.

So, my 42# bow likes a 32" aluminum arrow spined for 57 pounds and my 37# bow also likes the same 32" aluminum arrow spined for 57 pounds.

By shooting different tip weights, this allows me to shoot a variety of differently spined aluminum arrows no matter their tip weights because the dynamic spine and arrow dynamic spine will both be around the 57# mark for both recurves.

I have come to like an arrow that bare shafts a tad light

After I fletch they fly like darts

[JamesV]

The wood arrows that shoot best out of my longbow are underspined. My bow is cut to center with velcro sideplate installed afterwards with a B50 string

I am finding out after numerous arrows and months of tuning that the slightest and I mean slightest stiff spine makes me shoot erratic.  Flyers or shooting to the right (lefty) is my normal pattern.  Recently, I shot some arrows that I thought would be to weak and to my suprise they flew where I was aiming; even with a bad release sometimes. For me being a little on the weak side hides my shooting flaws and gets me close to the spot.

[SCATTERSHOT]

If they shoot well for you, from your bow, then they are spined properly. Guys worry too much about the charts IMO.

[lpcjon2]

My ? is I know some have been shooting for some time and for the new guys finding out under spined arrows are shooting well.I think that maybe they should check their form and consider they may be compensating for the arrow and its not the proper arrow at all.JMHO

[frankwright]

I think many are shooting over spined carbon arrows based on the spine the arrow is supposed to be.

I know lately some of the shooters around here are finding the 1535 GT arrows shoot very well in bows up to and slightly above 50#.

I started out shooting a 57# longbow with 5575 arrows and it never shot well until I tried the 3555 arrows.

[elkhunter45]

You're not alone. I shoot slightly underspined arrows better out of my recurve and longbow.
