Making 40 S&W bullets from 9mm cases

Now if someone would come up with a cheap way of swaging frangible bullets. That's the requirement at my club for anything other than pistol calibers. A 5.56 round costs just over $1 if you buy it there. :rolleyes:

wonder how your barrel likes that?

I was the thinking the same.

Bullet jacket material is gilding metal, 90% copper 10 % zinc.

Brass casings are made from 70% copper and 30% zinc....higher tensile strength than gilding metal.

Whether a gun barrel's bore will know the difference is the question.

The idea is quite intriguing!!!
 
I've read up on this before, and you have to anneal the brass dead soft in order to swage it properly. Once it's at the proper softness, there's very little difference between the casing jacket and a regular gilding metal jacket. Pretty cool, though. Check out the swaging dies at CH4D. Not bad for pricing. I just may invest in a set for my 45 ACP.
 
"...THAT would f**k up a CSI!!!..." It wouldn't phase Calleigh Duquesne a bit.
"...Any copper alloy is much softer than your barrel..." Yep. Brass will never hurt steel. Neither will bronze. Coolest thing I ever saw in a gun rag(except maybe Cooper's article about the 'Combat Brick' in SOF. Something you just had to see.) was an article about bullets made out of oil impregnated bronze bullets. Turned, as I recall. The oil smoked as the bullet went down range. Daylight trace without any fire hazard in very dry conditions.
"...Why would someone want to do that..." Because they can.

As luck would have it they have! Corbin sells a die set that turns spent 22LR cases into highly frangeable brass jackets for either .224(5.56mm) or .256(6mm). They are not cheap and I am currently looking at making my own die set to fit into a Lyman Oarnge Crusher. I'm thinking a .224 60gr HPRBT with a core made from carefully measured #12 shot gun lead.

I found this elsewere on the Web - hope it helps in making your die set:
"I can save you some trouble with this. The de-rimming die needs to be a little smaller than the .224 final diameter, otherwise the jacket will spring back and be to big to go in the core seating die.
A measured set is: the hole thru the die part is .217 and the pushrod that pushes it thru is .195. After shoving the .22 case thru the die the rim is ironed out and the case streches out to about .703 in length.
The new jacket springs out and measures about .219 that will go in the core seating die and when the core is seated it expands the
whole thing to .224." .

holy necro-posting batman...
That BTsniper guy is something else. the originator of this process over on the castboolits forum. I have followed all his posts, quite amazing some of his creations, I defiantly like the .308 projectiles he makes with FN 5.7x28 cases. Apparently u can also use the blank cases(they shoot the p90's in all sorts of movies and tv shows) to make the these aswell. A definite master swager.
