And you know this how? I suspect that the projectile will not
penetrate much. It is not lead, it is a pellet of fireworks, and the
stuff used is not dense.

My only experience was with a 12GA flare shell.fired at a concrete
block wall about 60-70ft away..

It exploded on contact with pieces bouncing back in our general
direction.

Previous test with a .22 rim fire, long rifle hollow point, didn't
penetrate a concrete block wall either.

Nothing very scientific about either test.
