need help with weight.

[Coues Archer]

I'am thinking of getting the easton axis arrows but i dont know the arrow weight i should get. i have a 27.5 draw length the draw weight is 65 pounds my brace height is 7.5 and i shoot a 100 grain broadhead. Please help I'am not sure with the way i have my bow set up if i need a size 340 arrow or 400.

Should be 400's. Easton has an on-line chart you can check it.

[coues krazy]

I would say 400 as well.

[BigBfever]

340/400 is that shaft weight or series? not knowing easton's to well I'd say with your set up your TOTAL arrow weight with broadhead, nock and fletchings should be 350-380 grain tops.

I would say 340 if your going after elk. Your right in between 340 or 400. I have a 27 inch 73 lbs draw and shoot the 340 (Full Metal Jacket). I switched from the PSE X-Weave 300 (which are much lighter) and my bow had a lot less shock and seemed quieter (but did not scientifically measure it), but it slowed down something like 25 fps.

 

The 340 at your draw including broadhead, flecthings, insert, etc will be around 425 grains.

i shot about the same as u and i shot a 440 grn arrow

My Full Metal Jackets weigh in at 436 on my reloading scale.

 

FMJ 400's

28" shaft

100 gr tip

AAE Max hunter vanes

 

I too switched from Carbon Force 300's only because I wanted to get my grain weight over 400 for elk. I can tell a difference in the bow shooting the CF 300's to the FMJ 400's. No trouble with the Carbon Force arrows and they've worked flawlessly on all the animals I've taken with them. Just wanted to get over the 400 grain mark ...and try something new I guess.

miguel1,

 

I too have the same drw,brace height and poundage(67lbs.). AR34, Just wondering what you were shooting before and why you are changing. Is it that your wanting more weight? I shoot the less expensive stl hunter 300 x-weaves. I have around 387 gr.per arrow putting out 270 fps. Missed alot of 3d's with this arrow and have become amazed by their durability. They fly great for my purposes using a Wac'EM broad head. Best of luck.

miguel1,

 

340 and 400 is the spine of the arrow. The 340's are 9.5gpi and the 400's are 9.0gpi. The 400's I shoot do weigh around 400 gr. with a 100gr tip at 27.5 in long. do not have the exact wait I lent out my grain scale. I think the 340's will be to stiff for the poundage and length you are shooting.

 

I just read your post again is your draw 27.5 or your arrow length 27.5? If your draw is 27.5 in most cases your arrow will not be that length.

[cmc]

and the FMJ 400's are 10.2 gpi.

I would go with the 400's. The 340's would be a little stiff at 65#s with a 100 grn point. I'm shooting 28.5" at 72# 340's with 125 grn point.

[Redman]

and the FMJ 400's are 10.2 gpi.

The 340 FMJ are 11.1.gpi. FMJ are bad azz arrows, but costly.

Using your draw length (keep in mind you are right on line for 340 or 400), if you go up in poundage you will be a 340. Easton makes multiple arrows that weigh differently (this is just an example, I would check the weights for your self). As Bownut said 340/400 is the spine of arrow, but as the spine changes so does the weight of the arrow.

 

100 grain tip

nock = 9 gr

insert = 16 gr

3 blazer vanes= 18 gr

 

With an Easton 400 9.0 Axis total weight: 390

With an Easton 340 9.5 Axis total weight: 404

 

With Easton 400 10.1 FMJ total weight: 423

With Easton 340 11.3 FMJ total weight: 454

 

There is a whole debate on Kinetic Energy vs penetration....but IMO I like a heavier arrow (425-450) when hunting elk....I went to Archery Headquarters and shot mutliple arrows and settled on the FMJ, Hard to get a heavy arrow with a short draw like us.

If you go with the heavier arrow you will need to do something to adjust for spine. There is a certain flex your arrow needs to come out straightest.

 

Up the poundage to get more flex. Most bows are close to the top of adjustment and don't have alot of room to move here.

 

Add length to the arrow so it will flex correctly. We are used to shooting arrows that are a certain length so this may feel akward.

 

Add weight to the broadhead. The shaft will flex more as it pushes against more resistance to initally get momentum started.

 

I say go with the heavier head and then fine tune your poundage to match the arrow and head combo.
