ethics is something you have to decide.....as for the bow...if it is a legal weight to hunt then I would ensure I had the sharpest two blade or three blade head I have that flies accurately. Lots of feathers to push through and a solid body as well... Personally, I would not use a bullhead at all...
I would not only be cognizant of my broadhead and bow setup but would also make sure I knew where to shoot for a good lethal hit from all angles...front, side, rear, etc.
I also would not be asking this question as turkey season is opening...it is something I would be testing and shooting and working on all winter to make sure I am ready and the items work as expected.
