There are 1 oz lead-shot-filled bean bags, as well.
A buddy of mine was using a rifle during some Antifa riots. It fired a bullet made of compressed cayenne pepper tipped by a small lead pellet. The pellet would break the skin and the pepper would burn.
It was pretty accurate and he had fun standing in the shadows and just picking off idiots. One kept coming back and getting hit over and over. He never knew where it came from.
Most took the hint and left.
