I'd like to up my draw poundage...

[Shinesintx]

This is the right way to do it. And yes, as others have posted, you could end up over 70#. Besides pin spacing, you could end up with your arrows being underspined too

And I gotta ask, Why?

Cause I wanted to? . 62 just got to easy and I was curious what the 70 pound fuss was all about. I'm gonna shoot about 30 arrows tomorrow and see what I think. If I don't like it, I'll crank it back down a bit. I was also planning on working on my 40 yard pin and wanted a little more oomph. Not that I would take anything more than 35. Mainly, I guess I was curious and could not leave well enough alone?


The bow is a 70 pound bow with 400 arrows. I am seriously wondering, as I don't know, is this a mistake in me doing this?

I would say you are under spined now.

What's your DL and arrow length? At 70#'s you might be under spined with 400's

28 1/4 inch Wildthing arrows, 400 (not sure what this means) 7.7 GPI. I have a 29.5 DL.


Thanks for the help and insight guys...this is a great learning experience for me. I was wanting to buy some new arrows...but afraid to.

Bump, hoping for an answer.

If you are going to shoot it at 70 I would buy 340 spine arrows.

Max!

Bottom it out, that's the way they were built to shoot

I aint trying start no big blown out deal but I was once told by a very well known Hoyt dealer that Hoyts usually shoot better at about 7#s below peak weight! Like I said I aint tryiny to start a fuss or say that I know everything but that is what I was told and believe me this Hoyt Dealer knows what he's Talking about!

[Shinesintx]

I think I'm gonna crank it down one full turn.

I shoot a Browning Illusion that is 72# (on the scale at Double G Archery) @ 28"

I pull 29 though and technically should have it adjusted, though I'm still very accurate @ 28.

I shoot 400 spine arrows. Do you really think this is a point of concern? I've never had anything weird or bad happen but I'd like to take this opportunity to get educated. :-)

Anyone?

Bump, curious also.

Proper arrow spine

1). Safety, there has to be enough stiffness in the arrow to withstand the sudden force exerted on the shaft upon release. Go watch a youtube video of arrows in flight. It is pretty amazing how much flex an arrow goes through when fired. Underspined arrows are not strong enough and make break and the end result can be a shaft stuck through your wrist.

2). Accuracy, properly spined arrows will hit where a well tuned bow is aimed. Read up a bit on arrow tuning. Too much information for me to type here on an Ipad.

As mentioned above, safety is a concern. At 70 pounds make sure you are shooting at least a 350+ grain arrow. Under that, and it almost like dry firing your bow. Next would accuracy, BH's fly much better with a stiffer shaft. With older slower bows you may have no problem.

I'm shooting 400 spine Aftermaths that are a full 30" long at 8.8 GPI. That's 264gr + a 100gr Hellrazor, plus the insert, vanes and nock, should put me a little over 400gr or so total, I believe.

Does this sound acceptable/safe?

All arrow mfgs will have have spine charts available. Read these for your arrow, type of bow and cam, #, and arrow length. This will put you in the correct spine. In most arrows a 400 spine is plenty for 70# draw weight. Also the heavier the broadhead the less spine the arrow will have.

You have plenty of weight. I would think it would be tough to tune BH's.
