RE: Muzzy Tuning
Nobody answered Pa's question. If the arrows are underspined then it doesn't matter what broadhead you use. The results are going to be similar. Need to know the bow weight, draw length, and arrow length to be able to make a decent appraisal.
And then throw the paper tuning out the window and get to braodhead tuning. As you can see, paper tuning shows you how the arrow is leaving the bow, but does not show what the arrow is doing down range.
