I or people I have hunted with have shot through the shoulder blade on that angle many times with great success...I have also been on way too many dead end tracking trips after 0 penetration into the shoulder....The strange thing...all the times I have experienced great penetration on the shoulder (or anywhere else for that matter) were with recurve bows, 600+ grain wood arrows, and Magnus cut on contact heads...I know I am a strong believer in shooting HEAVY arrows....
Makes 2 of us!!
