What is up, everybody? Mark on the mic here. My good friend, Mr. Ryan Muckenherne,

across from me right now. And today we're going to talk about a cartridge. A cartridge that

I find impressive, underrated, and frankly, Ryan, confusing. Because the more I read about

it, it's almost like the more I understand, but also don't understand. We're talking

about the rimmed, rimless, multiple, potentially multiple bore diameters. Like, when I think

of a cartridge, I think of it as like, it's this thing and it's this standard thing. But

the 8x57 Mauser, which initially wasn't even chambered in a Mauser rifle, it's just kind

of, it's a mentally its own animal to me. What the heck is going on with this thing? Which

apparently you have one, of course. Are you doing like, what do they call that? Mental

gymnastics? Yes. Okay, you're on the parallel bars right now. Yeah, but I keep falling off.

Okay, understood. So what Mark is talking about is the 8x57, or 8x57 Mauser, or 8 Mauser,

or 7.92x57 millimeter. A cartridge that has been on the landscape for a, and long time.

Real long time. 1888. Where? I was born in 1988. That's a good year. My, my dad had an

88 F250. In fact, it finally just gave up the ghost. Well, hopefully that doesn't spell

disaster for me or this cartridge. I don't think it will. Oh, thank God. 8 millimeter

Mauser. Okay, let's unpack this a little bit. 8 millimeter, 8x57 J, 8x57 JS, 8x57 JR,

S, 8x57 RIMD. These are all the same thing, but slightly different. Going to the bore diameter

component, 318 versus 323. And which one would have the 318 bore diameter? The original.

Okay. Yes. So early 1900s, a transition was made between the 318 bore to the 323 bore.

But the profile change went from a round nose to a spitzer type. And then we get 323, the

JS. Now our, it's thrown in there, designates a rimmed single shot stocking rifles, perhaps

double rifle, a drilling, maybe where you have that rim that captures that rifle or that
