I shoot some pretty big hardware and will give you my 2 cents.
If you shoot from a bench use a gun rest that is tall enough so you can sit up straight at the bench and fire the weapon. If you have to crawl up on it to shoot it from the bench it will continue to beat you up.
If you shoot it prone, be sure to do it properly, one of my shoulder mounted howitzers was purchased from a man who broke is collar bone with when he fired it improperly from the prone position. One tip here is to be sure and tightly grip the fore end with your non trigger hand.
This also helps firing from the sitting position, hold the fore end of the stock TIGHT.
