You need a silencer on your "Sport hunting rifle" so you don't have to wear earplugs. Also, you can shoot sitting ducks w/o alarming the rest of the herd. I mean, the old way made alot of noise and then they'd all fly away. That was a pain until the invention of the "bump stock". Now all you have to do is set up one of them exploding targets and shoot it. Then when the littler takes flight, you can just hose em' down and boom. Duck dinners for a year.
Also, say there's a bank robbery and two people were in on it? Once again, built in hearing protection. Also, if you shoot one of them, the other one doesn't know his back is no longer covered. Thus keeping the element of surprise.
Also, when you have to put the family pet down nobody hears it. You can just tell the kids Mr. pickles ran away. Sorry, but I can't help ya with an excuse for a hamster named Mr. Pickles running away, or needing to be put down. But that's the beauty of it. Nobody will ever know thus preserving your innocence.
