Something about your setup is out of tune.........fieldtips will cover this up but fixed blade heads will always show it. How do your arrows fly?? They can't both be flying flat and true and hitting so far off. One (or both) of them has to have less then perfect flight.

There are so many variables here that the best thing to do would be to start from scratch (thankfully it's not hunting season) and figure out what the problem is. Could be arrow spine, FOC, torque, form, rest contact, inserts, BH's, nocks, flecthing, draw weight, draw length, sight, peep, etc.

Lots of stuff that it could be.........most likely it is something simple. If you are not familiar with tuning your bow go to your shop and tell them your problem and have them figure it out (that what they are there for).

Don't let anyone convince you to move your sight THAT much..........if it was only bumping the sight a little bit (1 inch) then fine but being off by as much as you are is a definite sign of a problem.

Good luck..............and as has been mentioned already this is EXACTLY why I encourage everyone to practice with broadheads as much as possible. Imagine how you would feel if opening day was this weekend??
