Just paper tuned my bow and I'm shooting bullet holes at 10 feet. Screwed on my Toxic broad heads from Flying Arrow and I hit the bulls eye at 20 yards. I would say you need to tune your bow. You may or may not be able to shoot bullet holes at 10 feet but getting it close should improve your accuracy with a fixed blade broad head. I also found that with certain broad heads, you just won't get the same shot group as with field points. If your arrow is flying good then I would sight your bow in with your broad heads. I would rather hit where I'm aiming with them than the field points.

an arrow spinner may help, blades lining up with the fletching is an old wives tail, As Bronco said.
