For the OT2 guys. The Iron Mace is listed in the selection guide under "Newburry Iron Mace", not under HCA. You don't have to use the BT Pro 40 Dually. Not sure why they do not have it under HCA. I didn't find this out until this morning so my output was based on the Dually.
Also, if you haven't done so make sure to derate the IBO to match the speed for the arrow and DW that Swamp listed. WhenI ran the derated set-upthe arrowwas spined propery for 'Target' and 'Both' catagories and low for 'Hunting'.If that is the case I would think that for tuning purposes the arrow should fly properly? I'm going to run using the Newburry model tonight and see if there is any difference.
I was told by larry at pinwheel software that you don't want to derate the IBO but insert real IBO for a real IBO setup and then the program derates according to draw, extra arrow wieght, silencers, peepwieght, etc, and then use he performance slider to adjust for real measured velocity if you have that on hand.
