Hi guys - sorry I' ve been away for a bit and just got notice that you both had replied.... and thank you for your willing help!

Rangeball - the groups I mentioned were with field tips. I had broadheads but didn' t use them because I was afraid of ruining the blades and/or losing them in the round bales behind the target (paper). I have since decided to confidently sacrifice 3 of my six broadheads for practicing and was getting about the same performance but kept leading to the right of the target. I decided to crank up the draw weight to the max (70lbs.) and shot a few more arrows and they were hitting almost dead centre on the target - I darn near landed one arrow on top of the other arrow!

UpNorth - I' m using WASP broadheads, which after shooting a bit with friends and family I noticed that alot of them had the same broadhead assembly although none of them can recollect what they are... older bows that have sat a lot!
