arrows, #' s alum and carbon
As i mentioned in a previous post i am new so please help me out. I was told by the shop that i got my bow at to use 2415' s (Alum arrows). I guess i am trying to figure out what these numbers mean. I am having a hard time finding that number arrow locally and the cost is pretty high for a dozen. I am looking for alternatives and how i can tell they are alternatives by what the number " 2415" means. Also, i went to look at some carbon arrows and they were 60/70' s? what does this mean. thanks.

RE: arrows, #' s alum and carbon
Someone can explain this better than me but:
The Aluminum arrow numbers correspond to the diameter of the shaft and the wall thickness. 24 is the diameter and 15 is the wall thickness of the aluminum.
On the carbons the 60/70 of the particular arrow your looking at is supposed to be spined for a 60-70 draw weight.
There is a lot to learn and a lot to proper spine selection. I would suggest listing your spec' s on here and see what people come up with.
What kind of bow, poundage your shooting, arrow length,release,etc.

RE: arrows, #' s alum and carbon
Here is a good guide to use.
You just have to know stuff like draw length, arrow length, draw weight, cam type, fingers or release aid, and such.

RE: arrows, #' s alum and carbon
thanks i will check that out.
I have a Darton Striker, 62# draw, 29.5" draw length, 80# let off, and a true ball release. I am using 2915' s right now that i noticed were on the heavy side. They are about 31" long.

RE: arrows, #' s alum and carbon
Are you sure that the arrow is 2415, because it does not appear on my graph. Are you sure it isn' t 2315??? If it is 2315, you could save a bit of money by buying a xx75 gamegetter and using a glue on nock instead of a xx78. Gamegetters are about the least amount that you are going to pay for an aluminum with any type of quality.
northwoods 2915' s???? Those must be logs.

RE: arrows, #' s alum and carbon
I can' t believe you found a shop that didn' t try to set you up with carbons from the outset.[

Easton' s aluminum arrow sizes are pretty straight forward, but you have to have a chart to find out what spine (stiffness) they are.
Some carbons tell the spine range on the shaft, like GoldTip sizing a shaft 5575. That means a 29" arrow will work for bows between 55 and 75 pounds draw.
Some carbon manufacturers number their sizes by the amount of deflection they show on a spine tester. Some seem to grab a number out of thin air to put on their shafts. You have to use a chart to pick the right arrow for those two systems.
All the arrow manufacturers have their spine selection charts on their websites.

RE: arrows, #' s alum and carbon
sorry, they are 2219' s i believe.
the shop i go to actually recommended alum. I have found carbons today for pretty reasonable but just need to make sure they are the right length. Just want to sort out all the number stuff.

RE: arrows, #' s alum and carbon
Until you have shot a few years I feel you are better off shooting aluminums. Learning and understanding arrow spine, fletching, etc. is part of the process in the whole archery experience. This is coming from a carbon arrow shooter.
Yep, must be 2315. There are a few other sizes that you may choose to try at your weight and draw length, but you might want to stick with the one your pro shop suggested for now.
