What is up, everybody? Mark here. Join by two of my friends, Mr. Ryan Muckenherne. Pretty

much a staple around here. And repeat, guest, Mr. Ruben Alexen.

Yes, sir.

Now, Ruben, well, I'm going to say, I'm going to preface this. We talk a lot about here

about, you know, extending your effective range, long range shooting, ballistic, ballistic

calculators. Ruben, and we were talking about, you know, getting some, some ballistic

data the other day. And one thing that we were talking about and one thing that you need

to plug into your ballistic calculator is the BC, the ballistic coefficient. But there's

more than one. And even your calculator will make you select, you got to pick. And then

I always thought it was either G1 or G7, which I think I've actually been mistakenly

using the G1 occasionally printed. I got one of my printouts here. This is from folks

over at Kestrel, which we actually have podcasts with them at one time. So check, check

that out. There's like eight. And then one was like, Mark GL. But I think the, what are

the ones we need to concern ourselves with? Is it just the G1 and the G7?

We'll talk G1, G7, some solvers have a custom curve. Okay. And then we've got multi BC.

So that sounds like the one for me, because I don't like to pick. Yeah. Oh, what

yeah, within shooting, we'll talk about those probably primarily. Okay. Ruben, what is a G1 BC?

When does a person want to use that? Well, I'm going to preface this by saying when we give

this information, saying for most users, okay, in most applications, there's probably going to be

exceptions here or there. But we want to select when we're inputting that in the calculator,

whether that be in our fury A, B's or in our razor 4000 GBs, right? We're going to have to pick

something when we're selecting our bullet. We want to base that off of the shape of the bullet,
