RE: Penetrating the Shoulder Blade
I get considerably less KE from my setup (around 63lbs)and i have passed throughshoulders with Muzzy's and also Magnus stingers. I think you have more than enough KE. Thats not the best shot to take but I havent had a deer run more than 100 yards after being hit dead center in the shoulder. Good luck in Illinois this season.
