The Mind of a Bullet

Slide back the action, The hammer clicks, Reaction, Pin hits the primer resulting in a kick, I exit the barrel causing disruption. I give no thought to my victim, No mercy when I hit them, Shredding flesh and shattering bone, Pray one of I doesn't visit your home. Cold now, They try to remove me, Forceps grip the portion they see, I am pulled from my created cavity, Men shudder at the damage I allow. What am I, A piece of lead coated in copper, But packed in a casing with powder you can see, The death I have to offer.
