The only utilities that my SD has served todate:-
1. Oohs Ahhs from the beholders.
2. I wake up at 3AM with a weird urge to go full auto plinking & I do it in the lawn.
A practical application for someone like me would be if/when I wake up at 3AM I realize I'm Jason Bourne & OBL's watching a bellydance right next to my house :P
I use Chinese 115/124 gr FMJs, Pakistani POF +P SMG FMJs IIZ and Federal 147gr Hydrashoks.
HS 147grs are the queitest & leave less residue as compared to Chinese & Pakistani ammo.
