Hey you aluminum flinging guys, need help
 

I need help, not you :)

Based on recent discussions, I' m doing some modeling and supposing, but know jack about aluminum arrows. I know the first two #s and the second two stand for something, but what?

Shooting a hard single cam with a 100 grain tip, easton' s chart recommends 2315 and 2413 for a 27" arrow and 2317 and 2514 for a 28" arrow, all XX78s. Which is the better arrow for each length?

Thanks in advance...

The first two number represent the arrow diameter, and the second two numbers represent the wall thickness. In general, thicker walls are a bit tougher them thinner walls. Also, in general, smaller diamters will get a bit better penetration then wider diameter. For hunting, I' d go with the smallest diamter, thickest wall that is called for. for 3-d, just the opposite.

If if you are using these for hunting,

In your first example, 2315, 2413 (these are very similar arrows and there will not be much difference in the two), I' d go with the 2315.

In the second example, I' d presonally go with the 2317. But remember that the 2317 is quite a bit heavier then the 2514.

Range
From what I' ve seen, in those lengths, 2216' s work pretty much every time, doesn' t matter what type of bow(single, dual, hard, soft). I like them better than 2315' s...they are a little tougher.

BobCo is right. The first number refers to the diameter of the shaft in 64ths of an inch. The second number is the wall thickness in thousanths of an inch. So a 2315 would be 23/64" in diameter with a wall thickness of .015" .

I use a 2315 Arrow and have for the past 10 years. Be advised that they need checked for straightness just about every time you shoot one. They are fast and have very good penitaration on an Elk. I took a 6x6 Elk at 45 yards two years ago with one arrow and he droped on the spot. I use 3" feathers straight fletched..

2317 and 2514 for a 28" arrow mounted with a 100 grn head??? [:o] Are you crankin' some heavy-duty peak weight?

I shoot 33" 2315' s outta my round wheel compound at 60 pounds. I always spin them in the palm of my hand after shooting them, but after all these years it' s force of habit. I even do it with carbons. Maybe once in every 200-300 shots I' ve pick up a touch of wobble that' s easily tweaked out with the arrow straightener.

I won' t go any thinner than .015 wall thickness though. That' s the absolute bottom edge of the durability I find acceptable.

Also, I agree about the 2216. Those bad boys will shoot off just about anything, probably the most versatile size aluminum Easton makes.
