there are some companies that were selling rounds labeled as "glass breakers" that were effectively marbles with a mm rubberized shell. you don't want the solid nylon, too light, or the riot balls or weighted rubber, anything over 6 - 7 grams or so still lethal enough, but you gotta tweak the FPS way up to really pack the punch. slinghshot ammo should be solid if you have it either coated or in a shell to not damage your barrel yet still make a seal.
I have seen a few variations, my favorite is just ordering empty hard paintball shells and hammering out some lead to fit inside without bouncing around, and those are weighted around 15 grams, if you up your velocity to fire a standard 3 gram in the mid 400fps range, you can expect those 15 grams to deliver at LEAST 20 joules and you can easily push 30,
you got that coming at your forehead it's game over. will easily penetrate the adominal wall and shatter bone as well.
GOD FUCKING BLESS AMERICA!
