I concluded that the lack of complete pass throughs was due to my lack of KE(61#) as compared to those that were more satisfied with this particular broadhead and touted closer if not over 70#KE.
That's on the cusp of what "I" would consider the lower range.....but PLENTY for whitetails.
So what does this tell me? Is it 1)Wrong arrow for the reduced weight(Unerspined/Overspined)? I am shooting carbon arrows.
Don't know enough about your setup to say. Reducing tip weight will affect your spine. But...being over-spined isn't typically a worry I spend a lot of time on.
I wouldn't even bother with paper tuning. I'd have someone shoot my bow (with me watching from behind).....or get someone I trusted to view my arrow flight from longer yardages.....and BH tune my bow.
