Spine question

[gethuntin]

Could someonewith an arrow progam tell me my spine Out of a Hoyt vector 32 28" draw 70 pounds shooting a 28" axis 340 with a 50 and 75 grain brass tip 100 grain point and blazer vanes? Thanks

I can tell you if you plugged that arrow into an archery program that it would say you would be weak on the spine. That being said I know it will tune and shoot really well. Don't believe everything that those programs tell you as the gospel on what will and will not tune.

Thanks for the input, I am trying to decide between 300's and 340's.

 

[OR Archer]

Stick with the 340s. At 28" the 300 will be really stiff.

Do you have 225 total up front? I might be misunderstanding your post.

Spot on

I would either use a 50 or 75 grain brass insert with a 100 grain head. So either 150 or 175 up front.

If using a drop away when in doubt go to the heavier spine. It's nearly impossible to go too stiff with a drop away and I think you're on the edge of weak with that set up. Ya, you might get it to tune, but.....

With the brass up front weakening the spine I'd tell you to go 300 spine shaft.

I agree with above posts that spine programs and charts aren't the way to tell. I'd take your current arrow and paper tune it. If/when it does sight in and shoot Broadheads! There's your test! IMO

For reference I shoot an element at 70lbs 28.5 inch draw.
FMJ cut to 28 with 125 gr heads

FMJ injextion

Sorry fat fingered the send, typing this on my phone.

FMJ 340 28 inches 125gr heads. Shoot and tune fine

FMJ Injection 330 cutv to 27 inches VAP penetrator insert weighs 33 gr with 125 gr head shots and tunes fine.

You should be fine with a 340.

Well i have both shafts on hand so it sounds like i will be testing when the weather gets decent.Thanks you for all the input.

I tend to agree with Evan and tilzbow to go stiffer with that much weight up front. But you could get the 340 to tune out of the Hoyt

Go stiff or go home! You can't go wrong with a stiffer shaft. Stiff shafts tune much easier.
