Re: Arrow penetration
i pretty much have the same bow. Instinct set at 63 pounds with XT hunter arrows. I only use expandables for turkey. Bow is in tune, and I have done walk back tuning. Complete pass throughs on 3 deer. 13 yards, 20 yards, 29 yards. Slick tricks. I could shoot most any fixed head w/o flight issues. (I have tried many).

Your spot I NEVER go back
My spot I expect the same
