New Arrows

[Puncher51]

Alrighty guys, just deal with my ignorance if you don't mind. I've been a bow hunter for 10 plus years now but have never really looked into the specifics of my equipment. I'm hoping y'all can look over my set up and make sure I'm on the right track.

Here's my setup: Mathews DXT, 29" draw, and 70 lb limbs(I've got it turned up all the way). I've been shooting Easton axis 400's, at the out of the box length(32"). I can shoot great groups out to 60 yards and have really liked my arrows. But the problem is I'm just about out of arrows and need to order some new ones.

If my math is correct, my current set up with the long arrows and 100 grain BH I'm sitting at 432 grains, which is 6.17 grains per pound. If I used the exact same set up but cut my arrows to 30" then I'd be under 6 grains per pound which I read is a no go.

I'm looking at buying some axis 340's, so that gives me another 15 grains if my math is correct. I could also go with a heavier BH, but was hoping to keep my same BH's since I have quite a few.

What are yalls thoughts about my current set up and plans? Feel free to bash me if I'm off in left field. I'm just trying to get a better grasp on this and make sure I'm buying the right arrows for my set up. Also, who is your go to online arrow source?

You can easily shoot the 340's and cut them a little shorter. You can also up your broadhead weight. No problem. More draw weight equals stiffer spine. You will likley need some minor pin adjustments when you switch. Especially at longer distances.

once the season is over i'm going to give arrow smith a run with some of the arrows he builds that have a higher foc and weight. I've got plenty of speed want to increase the punching power and accuracy. Especially a long distance . . . .

Use brass inserts. And I don't know how you've got it tuned with those arrows. Seems way underspined with 400 spine arrows 32" long.

Any other changes or recommendations??

Before I spend a ton of money on 3 dozen arrows I want to make sure I check and double check all that I can.

You really only need 3/4 to an inch of arrow length past your rest. My arrows are 27.25 inches with a 28 inch DL. 71.2 draw weight 340 FMJs and 340 axis.

man you should be shooting 340s with that set up

Well you could go stiffer and probibly gain a improvement on grouping. So I would go with 340 spin, I use it in mine and it's not as fast a set up as yours. Things to keep in mind.

If you make the arrow shorter you are obviously dropping overall weight but increasing stiffness. Think about it, a shorter rod is harder to flex than the same rod that is longer.

Adding a heavier weight to the front, be it insert it broadhead, or both with cause more flex. When the arrow leaves there will be more weight up front it has to push to get going, this will act like it's less stiff. So the opposite is true, going lighter up front will make the arrow to act stiffer.

So if you do the two things you are thinking about you will be making it stiffer and then also making it less stiff. As long as you know that as. It's what you want you are good. If you doing know that you will have "strange" results and conclude the "arrow" isn't right, when it's really just not set up correctly for your gear.

If you can find someone here with the O2 program (I think that's what it's called) they put all the data from your bow and measurements to calculate the stiffness and arrow length you need, or at least get you really, really close.

Good luck.

Thank you very much for all of the very good information! Much appreciated! So if I'm reading what you are writing then you think I should go with the 340's and see how it shoots? No need in going with the 340's and also making the front end of the arrow heavier. I like that and that's what I was planning on trying first. I have a few unopened 100 grain broadhead packages I am wanting to use.

[Steel185]

Correct. Broadheads you can swap as you go, but once you cut them you are dedicated to that size or shorter. There are a lot of variables in arrow building, mixing them gets complicated.

[Puncher51]

alrighty, after doing some shooting this morning and measuring where the end of the arrow is, I think I'm going to go with a 29" arrow. May go 28.5", but somewhere in that ball park. Next question, any sponsors on this site sell and ship arrows?? I'd love to stick within the TBH family if possible. If not, I'm looking at lancasterarchery.com unless someone else knows of a better online bow shop.

Thanks and Happy Thanksgiving!!

That was my first thought, but if they shoot for him, ???

I'm about to buy 340's. I was going off what was recommended to me before. Arrows have always shot great with good results, but I need to switch to what my setup needs.

[wes122984]

340 cut to 28" with 100 grain bh or 125 should work fine. what rest are you using?
