If I hit the shoulder it is by accident. I used to do a lot of culling in Minneapolis with the Metro Bowhunters Resource Base.
The double lung shot is the only shot they wanted us to take/use.
If it works with a string gun then it should work even better with a chunk of high speed lead IMO.
Whenever I have hit the shoulder it seems to turn the meat to strawberry jello which looks to nasty to eat.
