I can take a 22 single shot rifle and do quite a bit of damage.
Very accurate and the projectile does bounce around like a ping pong ball.
Scratch a cross in the projectile and it will split apart upon impact and tear up everything.
course my Kimber 45 seems to do an even better job.
The .22 short sub sonic round is preferred by most professional assassins, but it has little penetration. Even a .22 LR minimag would have a difficult time penetrating 1/4” aluminum.
