Gas tanks don’t explode.

And shotguns do not spray out a cone of instant death and thus never need much aiming or practice.

For my first few years hunting the birds stood a hell of a good chance of getting away clean.

I’ve seen “pure” lead air rifle pellets make sparks against steel plates.

Military small arms bullets often have steel cores or have copper washed mild steel jackets. Sometimes both.

It’s all about turning kinetic energy into heat, not what it’s made of.

Yes, I’ve wondered how a non-ferrous metal could create sparks. Of course, you can get that effect with steel-jacketed bullets, but I don’t believe that they are standard issue for military and police forces.

“So in a way, you could argue that all of Hollywood’s gunfight bullshittery is a significant asset to our national defense. And, therefore, when Jerry and Matt transitioned from battlefields to movies and TV, they still played a role in fighting America’s enemies, through sheer misinformation. Keep that bullshit flowing, Hollywood. America needs you.”
