Bullet construction details.

I mean, these aren't any secrets, probably.

There's cup and core bullets.

There's plated bullets.

There's bonded bullets.

There's partition bullets and monolithic bullets.

That kind of covers.

There are frangible bullets as well.

Didn't cover those because frangible.

They're not very interesting.

So the cup and core, basically, you've got a cup of gilding brass, so copper alloy, and you smash a bit of lead into it, and then you do some subsequent forming operations.

And typically, these things have a jacket thickness between, I'm going to pick a number, 10 thousandths and maybe 35 thousandths thick, okay?

And you've got, because you've done

cold work to that jacket, they've got a fair amount of strength, okay?

In contrast to the plated bullets, which, you know, they're typically lead with a

three to four thousand thickness of copper plated on their exterior and the plating process makes that copper absolutely dead soft so when i mentioned before it's like toothpaste in a in a bag of tinfoil that's not so far from the truth okay so the these bullets don't have a lot of um let me use the word structure or phrase structural robustness okay uh i did a job for a

company that was doing a development on nine millimeter handgun last year.

And they were, they were they were very happy with the accuracy of the handgun, the group sizes that resulted with the exception of one,

manufacturer that happened to use a plated bullet.

And it was kind of a, let's just say, budget-minded offering.
