Arrow Identification Help

[tracker12]

I found an arrow over the weekend that flat out shoots bullet holes out of my #43 RER LX Longbow.  The arrow is an Easton XX75 Blues 29" with a 125 grain head.  I'm just not sure what size it is.  The outside diameter is .281.  I measured an XX75 1916 and it is right at about .3.  So does that make the Blues I found a 1816.  I found the Blues online and that seem to come in 1716, 1816 and 1916.

Sounds right to me.  Shouldn't be to hard to find another to confirm.

Doesn't it say what it is on the shaft ?  Look below the "Blues" logo ( spin the shaft around)
.281 is 18/64

A 1816 arrow shaft is 18/64 in diameter and the wall is .016 inches thick. etc...

Thanks guys for the info.  Marking must be worn off I was unable to locate the size.
