I'm shooting easton's xx75 camo game getters does anyone know their GPI for them is?

You are going to have to give the size to get an answer. There is a four diggit number on the shaft that will tell the size.

Guess I have been gone too long...LOL

What is GPI (guessing grains per inch) and what can we do with it?

I believe it's 12.2 g.p.i. Great arrow !

when you know your gpi you can add up all of the weight of your arrow and then divide the total sum by your arrow length and you want to be at least about 9 gpi so you don't damage your bow,thats my understanding. the heavier the arrow until a point will be effective against your determined animal of chase.

I gotta say i love them so far! i wish it would warm up here ( its literally 0 out) so im stuck shooting them in my basement which is better then none, but i'd love to get some 20 and 30 yard shooting in!
