Ricochet, perhaps, if fired too closely at steel targets. I concur it seems unlikely an Army CSM would have difficulty managing even 500SW, certainly not 50AE, from a serviceable firearm.
I did fail to press that point...SERVICEABLE...as I assumed anyone with that type of weapon would not have anything other than a serviceable one.
However, stranger things have happened.
As far as ricochets, I saw a kid popping NATO SJ 5.56's at a steel disk designed for .22 popups.
About the fifth round, a piece of steel broke loose, hit the concrete back stop, showered him with concrete shrapnel and the contents of the round sans the steel jacket and scared the hell out of him.
I think he learned a good lesson.

Why? Because they occasionally qualify on a heavy framed 9mm? Hell anyone can do that.
