Aluminum arrow help/spine choice

[NY Yankee]

I'll order a couple of each spine and test them . It'll be a minute  before I order but if I can remember I'll let yall know . I'm really interested now . Never gone down the aluminum rabbit hole .  Thanks for all in the input and knowledge. Anybody else is welcome also
Thanks

The one thing about aluminum arrows is that the spine consistency is much better than carbon shafts and much easier to tune.... The down side is that they are easily bent, and no amount of straightening will ever bring 'em back to new.

I used to hunt with alloy shafts years ago..... but the first few times you take a fall and bend a whole quiver full of arrows 3 miles from camp, you'll start thinking about going back to carbon shafts again real quick.     Just saying....

I think if hunters had so many problems bending arrows when all there was was aluminum, there would be a lot less bowhunters than there are now. If you take a fall enough to bend your arrows, I think hunting is now the last thing on your mind.

Lets just answer the question at hand. Just saying....

The OP stated he was considering trying aluminum arrows for hunting next fall. I was just trying to be helpful pointing out the higher quality spine consistency , but poor durability issues that we don't have to deal with anymore with all the modern carbon shafts available. Carbon is either dead straight, or broken.

As far as the what size aluminum shaft to start out with question goes,  there have been several recommendations already than can be tried, as well as other options.

but the center cut on the shelf depth , and strike pad thickness will dictate the tuning as much as draw weight will.      Good luck my friend....    Kirk

Dark timber carbons are +/- .006.  XX75 are +/- .002.  To me that says aluminum is 3 times straighter than at least that carbon.  But for me with 200 gr broadheads the aluminum needs to be stiff, ie 2216 or 2219.

My first thought was 2016 or 2018, but the 300 point up front would throw me. I would still think 2018 but you would be best with the test arrows.
I never worried about bending aluminums especially with the thicker walls like 2018. I shot them for years and years and had to really abuse them to bend one and then I would just straighten them.  Easily done.

I'm a fan of 22xx, 2215 would be lighter than 2117 but real close to spine.  2020 might also work OK.  I've never tried that much weight up front with aluminum, 175-190 grains has been about tops.

I am assuming your draw weight is approximately 46# @ 28" based on the mfgrs figure of 52# @ 30". The spine chart covers a range in point weight 100 - 190 grains. If you stay within that range you will find a nice balance for your bow. Over-loading the front end will cause all kinds of negative consequences. Even if your bow is super fast, which it probably isn't your going to face a very slow arrow that a turtle could jump  and your range will be very limited.  I know a girl that killed a big bull elk her and her Dad told me she has taken two cow elk since then. It doesn't require arrows with extreme FOC.  Here is a link to the spine chart from 3Rivers. You would have an option of 160 or 190 gr. head on the 2016 or 2018 shaft.
