Go to first post for story conclusion.
I was shooting a full length Beman Centershot, 50g insert and 125g Magnus Stinger 2 blade. I had brought 225g Centaur Big Game heads with me, but went with the Stingers at the last minute because I was not confident in how sharp the Centaurs were, I still haven't perfected my skills sharpening concave single bevel heads. The arrow with the stinger out of my Centaur, 58# at my draw length should have been enough to do the job. Hitting the shoulder bone did stop the arrow though, as the arrow was never recovered. I am going to invest in a grinder/paperwheel setup to get the 225g Centaurs super sharp and once I do that they will become my go-to head.
