Swaging .50?

So, after shooting a friends Barrett 82a1 and talking about ammo prices I got to thinking about swaging .50 BMG bullets, I know .22LR brass is used to make .223 bullets but is there any common (cheap) brass that can be used to make .50 bullets? I ran my calipers over some of my fired brass and the closest i had was my 8mm brass comes out around .470 where a .50 BMG bullet should be .510, since brass cased 8mm isn't free or all that easy to find laying around I was hoping someone had an idea on what brass could be made into .50 jackets which is reasonably cheap/free and fairly common. Thanks

Included is a pic of 9mm brass as .40 S&W jackets.

That's a FULL seamless copper jacket covering the ENTIRE CASE AND BULLET without any break/weak-point to separate the bullet from the case? Might that not cause case head ruptures before the bullet separates (unless it's scored around the top of the case) - or possibly causing issues with protruding primers?

Now THAT'S pretty cool!

I had a friend back in Omaha who used to use .22 LR cases to make "practice" bullets for his .220 Swift. They were almost as accurate as his factory bullets, and a lot cheaper to shoot (unless you counted his time to make them).

Of course, this was a guy who would regularly re-barrel his rifle every two or three years, and I've seen him hit prairie dogs at over 800 meters. So he shot a LOT!

You may need to look at Corbin bullet swaging options. I can't think of an available case that would work.

Mike I think that the idea is that those are just bullets, not entire cartridges.

Okay, I claim ignorance - WHERE would the cartridge end and bullet begin (in that picture)? Would that actually be a "caseless" cartridge?? If so, WHY haven't we been doing so for years?

I'm just looking for education, and if such a thing is possible, why are we holding back on such production?

that IS the bullet. The 9mm case is swaged over a lead core to form a finished bullet. Don't let the rim distract you -- that's a red herring.

It's just the bullet base now. The rim is just an artifact that remains from it's previous live as a cartridge case. It's a brass jacketed lead core bullet instead of a copper jacketed lead core bullet.

just follow the bouncing ball from cartridge casing to bullet jacket to loaded in a .40SW cartridge

Usually, they use copper tubing to make bmg jackets, or if a full base is absolutely required, caps.

Swaging, is not economical, the presses, and dies can cost truly stupid amounts of money - a Walnut hill press from RCE is what? 400 bucks these days, with a how many month wait?

Swagings big advantage is you can make bullets for anything no matter how oddball the size - 227, 318, 298, 318, 435, etc. Even bonded bullets are now easy for something where a commercial offering doesn't exist, has few, or spotty suppliers.
