My had lost about half my axis FMJ's. So I set off to the archery shop to get some cheaper arrows (some thing a little cheaper than the fmj's). I told the owner what my draw length/draw weight (29" draw/ 70 lbs./ 100 gr. heads) and he told me i needed 400's for proper spine.I say okay,and pickout awrap for the arrow.Icame back about 2 days laterhe charged $135for the dozen. I take them home and shoot them and isome sort offish tail/ barrel roll out of the arrows. now I look on the easton charts (on there web site) and it looks like I should have ordered them in the 340 size instead.

am I right??
If i am are these arrows now junk? I think they should be good on a lighter poundage, if so I might be able to sell them. if not then looks like they are going in the trash.
HELP!!!
