First let me clarify, my draw length is 31.5, I am shooting an overdraw w/ 29.5 arrows. Over the weekend I had 6 arrows refletched w/ feathers. That took care of all of my hits to the right-makes me think there might be a little clearance problem, but I can't seem to find it. The broadheads I am currently working w/ are thunderhead 125s & muzzy 100s. At 20 yds, it seems the muzzies are slightly more consistent, but not much difference at all. Right now I would be very comfortable w/ either broadhead, but I will continue to tinker @ this range until after my bear hunt in 2 weeks. After that I will move back to 30 & 40 yards to see if they continue to fly as well down range. Thanks for the input & don't stop replying if anyone has any ideas on fine tuning my setup.
