shoulder penatration

[KAZ]

Lots of good info already stated... I have some recent experience to share. I've always followed the Ashby Studies and to me it's hard to refute. Yes, there are success & failure stories on both sides of the aisle, but physics is physics and I think you can set-up your arrows for better bone breaching capabilities. Trajectory is a trade-off depending on how far you really need to shoot. For me out of Treestands or 20 yards and under, the trajectory is not a big deal... Here's a link to a thread I just typed up, and on Page 9 I just updated shot specs & pics! Great advice is to not hit the shoulder bone (at least on entry). But, we're not perfect AND the animal doesn't always cooperate...

By the way, this year was my first year to dial-in the heavier arrows with High F.O.C.. I finally pulled the trigger after years of following Ashby's studies AND listening to him speak @Kazoo :-)
