After may days of tinkering and tuning and bare shafting and pulling my hair out I've resigned to the fact that "it is what it is".
Jbrown is seeing about 12 inches of drop from 20-40 with a 506 grain arrow. I'm shooting 1 grain heavier and seeing 21 inches of drop. Same bow, same draw length, same poundage. He measured up his bow and I dialed mine to those exact specs. Brace height, ATA, top and bottom cam time to the 32nd of an inch, rest height, all identical. Paper tuned & shooting bullet holes..... Guess what.. Yep still 21 inches of drop. Talked to
@Milo last week and he recommended bare shaft tuning at 20&30 yards to get the bare shafts hitting with the fletched shafts...
Yep.. Did that..

Guess what... Still about 21 inches of drop. The below was shot with the 20 pin at 20/30/40 yards.. About 7 inches of dropfrom 20 to 30, and then an aditional 14 inches from 30 to 40
