Aluminum arrows - Can anyone tell me what the Easton numbers 300, 400, 500, etc mean?

I know the 2315 etc. codes, but they are not on my arrows. Mine say Easton Gamegetter 300 xx75. No four-digit number.

I can't find them in the Easton chart.

Can anyone crack the code for me?

THANKS

I'm not a 100% on this but I think on carbon arrows it represent thousanths of an inch deflection when the arrow is supported on each end and a calibrated weight is hung from the middle of the arrow. The larger the number the softer the spine (on easton/bemans anyway, however carbon express is different they also have 200/300/400 but the larger the number the stiffer the spine but I'm not sure what the # represents in that scenario) I'm not sure if this also applies to aluminums or not

hope this helps

i know with my goldtips .. my numberis "5575" it was explain to me that its the range that these arrows can shoot at.. 55lbs to 75lbs..

atleast thats what the feller said to me at the pro shop..

dont know if that will help...

This is the right answer on all counts. No reason to et into the technical part of spine testing unless you have a spine tester. If you want to compare a carbon with an alminum the arrow charts usually show a deflection number there for the aluminums. For the record, Easton is the only arrow maker that marks their arrows so we know what the spine is.

And be careful with the Gold Tips, too. They designate their Ultralite series like Easton, but the XT's need to be relabeled. The 5575 is a 400 spine so is way underspined at 75# unless the arrow is about 24" long. Get those 5575's around 29" long or more and they're only good for about 65#. It can get pretty confusing for novices.

Blackhawk is like Carbon Express except that they add another zero. Spines are 2000, 3000, and 4000.

Easton FMJ's are marked like their carbon arrows.

Don’t let any one know that I told you this(it’s spy stuff). The # relates to the spine.

500 is a 2016 spine is .531
400 is a 2117 spine is .407
340 is a 2315 spine is .342
300 is a 2317 spine is .297

And remember don’t let any one know that I gave you the secret code.

Thanks Mike. I don't know if I can trust you, but it will have to do for now.

Actually it does make sense. These arrows are tree trunks but should work well for my 70 lb recurve with a 31 inch arrow.

P.S. Buy low, sell high.

mike.....where do you get a 3117 aluminum? I though 2613 was the fattest shaft Easton offered.

Typo!!!!! I'm sure he meant 2317.

I'm waiting to see.

I caliperedthe 300at .369 inches.

.369 x 64 = 23.62 64ths

So BGfishershould be correct - a 23xx or 24xx. 31 must be another code?
