I could write a book on shoulder hits.

#1 Opposite shoulder on a buck, shooting a 60# compound & alum arrows at about 12 yds. Broke the far shoulder bone, and stopped the head, no exit. Rocky mountain razor broadhead

#2 Again opp shoulder, 14 yds shot on a buck, 70# bow, thunderhead 125 BH, head punched thru skin on far side. The bone was broken on the ridge part.

#3 Doe turned on shot, hit the near shoulder just below the joint. Same setup as above, arrow put a chunkout of the bone, did not break it, but dislocated it from the joint. Got very little penetration, 5" at most. Arrow fell out after 50 yds

#4 Opp shoulder on abuck at 13 yds. Broke shoulder at ridge again, no exit at all. same setup as above

#5 & #6Almost identical shots on does, very close 5yds, arrowblowing thruthe thin flatpart of scapula. Complete pass thrus, with same setup.

None of these deer went more than 80 yds, with most under 50. Deer #3 went well over 200, but had good blood all the way.
