i can tell you that a 120 gn hornady in my 7mag will ruin twice as much meat as a 140-165gn . i think with any big caliber you really must stay off the shoulder to save meat. the best shot with anything is right thru the ribs.
with the 7mag if and light bullets if you hit far shoulder on exit you will lose the whole shoulder in most cases.
