I personally have not shattered the shoulder of a deer with my bow set up only with a 30-30. Most of my deer shots have been placed well enough for pass through, but last season I took a 293 lbs hog with my heavy broadhead set up. I shot the pig a little high which barely grazed one lung, then the arrow passed directly into the mammoth shoulder of that sucker. The shoulder stopped the arrow but the broadhead cracked the shoulder. At initial impact it actually knocked the hog over, he got up and ran real wobbly towards the palmettos, a few seconds later he crashed 40 yards from my shot. He never bled so luckily I could see him when I got down from the tree. When I skinned him, I got my broadhead and a piece of the arrow back. The shoulder had a 2” curved crack in it almost the shape of an “S”.
I shoot 70lbs, my draw Length is 32”, I shoot 32” arrows, with the broadhead, insert, right helical feathers and my knock my total weight is 653 grains. My clocked arrow speed at the indoor bow shop range is 239 FPS which is very slow BUT the silence and the impact of heavy arrows with single bevel broadheads is unbelievable.Occasionally on a pass through the animal doesn’t even act like it knows it was shot. Other times like that hog, you hit a blunt object such as a shoulder and WAM! It knocks them clean over
