Wow that is an interesting way of doing it! By chance you have any pix to show how you do this?Your Best arrow flight is going to be Tuning you Bow. I use a Laser for the left and right adjustment. and Then use my rifle boresighter ( laser) through and arrow shaft to check the point of aim with my sight.
X2 - except I'm not as good as Stubbleduck :wink: and only got one tom (12yd) with the 100gr bullhead.I used the 125 grain Bullheads with FOB's last turkey season and plan to do so again this year. I didn't change anything from my whitetail setup, just screwed on the Bullhead and went hunting (I did test shoot a couple of times first but made no changes to the setup). I shoot a 100 grain mechanical broadhead (NAP Spitfire) for deer so was a little concerned with the switch to a 125 grain Bullhead. Out to 25 yards (That's as far as I am comfortable shooting at a turkey neck) they worked just fine, taking two Toms in the same morning (Kansas).
