A silenced weapon has tactical advantages for hunting tree-rats and wabbits after SHTF
I was using 22 shorts in my Ruger 22 but loading was a PITA, one by one by hand.
Here's CCI's 22 CB Long ammo that feeds from the clip without all the hassle.
Deadly quiet, no FFL tax, stamp or other Fed B.S. About 700 fps at 30 gr / equal to a high powered spring piston hunting air rifle but a hell of a lot more quiet.
