I always presume anybody with a gun doesn't know Shinola--it's definitely a lowest common denominator issue since the round doesn't know the IQ of the person propelling it into the ether. Pretty much everybody I know who carries/carried a weapon as a profession rolls their eyes at the typical gun enthusiast.

A note on making your presence known--given unknowable acoustics and the possibility the shooters are wearing earplugs, never, ever, ever assume you will be heard when shouting at the top of your lungs. I usually carry a whistle, but even that is sketchy at times, dissipating after a short distance in the woods.
