Hi gang,
So, I got some AD Trad heavy and Hammer head Heavy, spine 55# - 70# to shoot from my BW 56# at my draw.
I also have my old ones, CE Heritage 250 cut at 29,5 with 100 gr brass inserts and 145 grain point.
I wanted to get, on the AD's, around 200 gr point with 100 gr inserts.
Using Stu's calc, if I cut the AD's Trad to 30 I would get slightly weak and the HH, cut at 30 7/8 also slightly weak.
Received the full length. Installed the regular insert (26 grains) and the 100's ones on some bare shafts. Started shooting by the method of bareshat using my field test kit. Either with the regular and heavy insert I got always stiff going from 100 grain point to 350 grains point!!!! The AD Trad got near the sweet spot with 100 grain insert and 250 grain point, the HH never got close!
Then I started thinking I was going to heavy on the end. I fletched a couple and shot with the bareshaft.
The point of impact was the same but the bareshafts flew sideways hitting with nock left. I'm left handed.
Then I thought my form was getting me these bad results so I shot some bareshafts of the CE. They fly strait as bullets.
What can be happening here?
Thanks for reading in advance.
