Okay.

And pardon me, I've got a cat pestering.

That's a cat that's been fed.

Okay.

Any questions here?

All right.

And I'm going to see if I can find some way to see them.

All right.

I'm not seeing any questions on.

Okay, so the next slide here, general cartridge case design guidelines, and this is for brass.

Okay, so, you know, things that have to happen.

First is a tapered case body, and that makes the extraction easier.

And kind of the steeper the taper, the easier that becomes.

So it's a matter of what's the press fit when you're done firing and how far do you have to move the case aft.

till the press fits removed okay um so so if you look at the like the new cartridge cases like uh six five creed more uh the prcs those case tapers are pretty shallow compared to military cartridge and that i mean since we're not putting them in a machine gun

Kind of no harm, no foul.

But if you're going to put that in a machine gun and operate in, let's just say, less than ideal cleanliness conditions, you might be disappointed with the performance of those cases.

Okay.

So the next item is tapered wall thickness, and cases are always thinnest at the mouth, thickest at the aft end.

And the reason for that is you want the case to seal at the mouth first so that you don't get any gas leakage past the cartridge, and you don't get any gas residue that gets deposited on the case aft of, say, the neck, okay?
