And so for

A typical, like say 5, 5, 6, I worked with 5, 5, 6 a fair amount over the years.

A typical worst case percent of ultimate strain might be only about 60 or 65% of ultimate.

So there's usually a fair amount of margin there.

just because of the reliability requirements that are placed on the ammunition.

So here's a slide that shows the forming steps for a brass cartridge case.

You start off on the left-hand side with a cup.

And then you do the first draw, you do the second draw, and then you preform the primer pocket.

The next step, you draw a little more and you do another preform on the primer pocket.

The third, what is that, the fifth step there, you put the extractor groove in, and then moving further to the right, you put in the shoulder.

You basically preform the shoulder.

And then the second to the last step, you'll notice that that case has been annealed.

And because you're putting so much work into it,

That's going to need to happen during the forming process.

And on the last step here, it shows that the primer, I'm sorry, the flash hole has been, okay.

And each manufacturer has their own series of steps that they perform in order to make a cartridge.

And they're optimized for their factory.

Shall we move on?

Okay.

All right.
