Suppressed rimfire, from as secure of a location as possible, makes quick work of glass bottles. Aside from the smell, toasted commies don’t bother me.
22LR subsonic from a 16+” barrel does not even need a suppressor during any kind of a “protest march.”
Try it at the range, outside, you will agree. Most of the noise from 22LR fired from a rifle is sonic crack. Going subsonic solves that.
22LR from a pistol means both a fairly significant muzzle blast plus sonic crack with standard velocity rounds. There is not much payoff shooting subsonic from pistols.
The real jackpot is 22LR subsonic from a long barrel. No suppressor required.
