You are looking for an ARROW with a .300 spine deflection.
all 3 are good. Would you like a heavier or lighter arrow? In the same spine that is all you are really changing. You must have a long arrow or 125 gr Broadheads.
I shoot Axis but I have shot ACC's.
What didn't you like about the injexions? If you didn't like them I doubt you will like the axis, basically the same thing except I found the injexions a little more durable, and obviously a little skinnier.
FMJ's, I used those for a good bit of time. Bent quite a few of them. If your really careful with your arrows they are a good choice. Im glad I shoot the injexions over them now.
Cant speak for the acc line, but they do have the ability to bend as well.
Coop, have you tested/thoughts on the Easton Epics (discontinued I know)?
And, since the OP is inquiring about the smaller selection of .300 spine shafts, what are some of the better options out there currently in that spine?
I was talking with a buddy who has done meticulous testing at longer ranges recently, and he is getting the best groups with the Injexions. The only thing he doesn't like about them is it seems the stem of some of the field points are bending a bit, causing them not to spin true. Not sure if anyone else has observed this. I did notice that a few of my Injexion field points don't spin true right out of the box.
