This is good advice. Download the manual from easton and read it. It tells you how to broadhead tune.

Sounds to me like your rest is off or you are shooting a spine that is seriously to small for your bow. If you are shooting 65 or more Lbs. you should be shooting arrow with a spine of 340 or 300. I had this problem years ago after my shoulder got better I was trying to shoot my old 400 spine eastons at 70lbs and that coupled with the fact that my rest had moved a little, caused virtually the same effect due to the fixed blade broadheads catching a little more air than my practice tips. By the way you are shooting a real fine shaft, I know I build arrows and do a lot of test shooting

Did you install a BAR (Broadhead Adapter Ring) on your arrows? For Axis arrows, you should be using #4 BARs. Reference http://www.eastonarchery.com/products/product/6

This sounds to me like a tuning (tweaking) problem. if your field tips and broadheads are both grouping well but with a different POI, then you need to do some fine tuning of your rest and/or nocking point until both hit same POI. Take the advice of the guys on here and download the Easton bow tuning guide. If your bow is shooting FTs well, it shouldn't take you long to fine tune it.

I use Eastern, But I use the Eastern flat-line 400, Great, in matter of fact, I did hit a brick wall and no damage....I have the same 12 arrows for about 6 months now, I shoot about 3 times a week, great arrows

Just had to leave something on this...

Don't forget to pay your taxes...12 million illegal aliens are depending on you!
And bubba is depending on the illegals for their votes!

This is very funny. they should let hunting season start on the borders, that way we can get practice for deer season..
