Tarkov silent caliber: Quest help

Hey there, how's it going? You know, sometimes you gotta go kill someone in close combat, and you gotta do it quietly and properly. I prefer a 12-gauge for that, and I have no idea why the guys at USEC and BEAR don't like it. It's a reliable caliber, you know? You just have to get as close as possible, and if you have a suppressor, man, you can take people out without alerting the guy on the other side of the wall. It hits silently and it hits hard.
You need to learn how to control it while I think of a good way to make your “talent” profitable.
