Has anybody tried making lightweight copper bullets for pistols?
Liberty makes a 9mm 50 grain that has a 2000 fps muzzle velocity.
I was wondering if you could make a truncated cone HP or other design from a copper rod that could get down to that weight. Or is there another material that would work such as a soft aluminum?
I would think a light material like aluminum would be a goid choice. You would want some length in the bullet. If you have a mini lathe just make a handfull and see what happens.
If you get a 9mm auto to function it may be too harsh on the gun. Would be a cool idea for revolver
Zink is self lubricating, tough and light (ish) and easy to machine.
Used for cattlekiller rounds in europe back in the day.
Back in the 1980s, Kendall International marketed "Equaloy" .38 Special ammo (sorry, no 9mm that I know of). The aluminum alloy projectile was the same size/shape as a lead 158-gr SWC, but only weighed 38 grains. Muzzle velocity was supposed to be 2000 fps. The projectile had a nylon coating, reportedly to prevent shedding aluminum in the bore.
I second 17nut's suggestion for zinc - it can even be cast - this RCBS mould would drop zinc bullets weighing close to 60 grains -

Ammo made with wooden bullets was used by the Japanese in the late stages of WWII. Wooden bullets made nasty wounds is close jungle fighting.
Last I heard people were having to spin cast Zinc bullets (centripetal force helping fill the molds), did they figure out a better way?
Company called guncrafter industries turns solid copper bullets for their 50 caliber handguns. The 185gr is 1200fpm nice hollow point that butterflies well.

That could get interesting for the home caster!Quote:

When I was casting zinc slugs 20-some years ago, I kept the mould blocks hot by sitting them on a small electric heating element - vaguely similar to this thing -Quote:

I finally lucked out and bought an ammo box full of 9mm ZEE slugs on Gunauction.com...... my zinc-casting days were over.
I used to make my own "Glazer" slugs for the 38 SPL. I melted the core out of 125 gr Jacketed then filled the cup with #12 shot mixed with epoxy. They weight 60 gr and I pushed them at 1600 fps (just under the SAAMI +P MAP). They were absolutely devastating. I put down several injured deer and smaller animals with them.
I might try melting the lead out of some FMJ bullets and putting a lighter core in it with epoxy.Quote:

Many moons ago (1903) a mad Dane (Schouboe) made a .45 pistol and that with pure blow back, no delays of any sort.
To make the thing work and not destroy itself in short order he had DWM develop and make aluminium jacketed (later nickel clad copper) wood projectiles. 62,5grains for a .45 how's that for light?

Very interesting ! Wonder what the reasoning was for his creation ? Short range target? Maybe just because he wanted too and could ?Quote:

And as i said blow back with no retardation to slow reloading timing down.
You can do that with mass in the bolt (most MPs) or some kind of mechanical locking (1911 and the lot) between slide and barrel.
The Schouboe had a light slide and no locking mechanism.
I tried some of the home made glasers (including one for 223 with the jacket from the old 70 grain Speer SP) and have tried wooden bullets and the like. But I came to the conclusion that, for me, they have no use. They have limited range and are troublesome to make. With the very limited exception of dispatching animals at close range with limited penetration, there is nothing that they can do that a typical bullet will not. So yes, you can certainly make light weight solids from copper rod. I just don't see an advantage.
I forgot one more use. Light, frangible bullets can blow up water jugs in spectacular fashion. A lot of fun and a big Wow factor for spectators.
