Bummer. But no matter, I no longer have access to a machine shop anyway :(

Good to know though, thanks

Much better material for the job is out there and not on the list. At best even with machinable tungsten all you could end up with is a crude core with limited performance.

You have to think outside of the box.

My T6 rounds act like FMJ's while penetrating yet do massive tissue damage.

Did you know you can get Aluminum, Lithium and, not quartz but a crystal type that I can't remember just now, alloys that maintain the weight and density of the host Aluminum yet are almost as hard as Tungsten?

And the sh!t I am playing around with MIM and ceramics.

Oh just you wait, in about a year when I have money from my brass to pay for the R&D.

Ceramic cored bullets, or MIM cores in copper jackets.

With MIM you can mix up all sorts of fun alloys for light weight, yet very hard.

I really should leave the bullet building to the pros anyway. But you did pique my interest in the ceramic thing, I've had a couple of ideas on that for a while but lack the knowledge to do anything about it yet.

Are you thinking of Sapphire? Very hard mineral...It has a Mohs scale hardness of: 9.0 which is in the mineral family corundum, an aluminium oxide (α-Al2O3) witht race amounts of elements such as iron, titanium, chromium and copper.

My other expensive hobby is collecting gemstones. :)

Have there ever been any bullets constructed from any type of mineral crystals?? Sapphire is the third hardest mineral behind Moissanite at 9.5 and then of course diamonds at 10. They also seem to make watches tick better when used as bearings due to low and predictable friction, good temperature stability, and the ability to operate without lubrication and in corrosive environments. They are known for their low static friction and highly consistent dynamic friction.

I have to look it up. I found out about when visiting a metals plant that only manufactures alloys for the areospace industeries.

I don't suppose you would get very good expansion with a hard crystal tip on a bullet but it might make for a very good penetrating round albeit a little on the pricey side.

I don't get expansion with the T6B ether.

What if you made a hard crystal core with a soft hollow point that explodes upon the proper hydraulic pressure. That way you get penetrating and a good wound cavity for expansion.

Just got a sample of bullets and these have been around in the past.

They are cut down 109 and a <profanity> nightmare if you shoot them.

There is a thread in the private section of the forum concerning these bullets back 2008.

This pic is mine, that I posted of back in 2008 and are identical to the bullets I am holding in my hand right now.

Thanks Jay. I love my pistol, and my hand-fingers even more!

GONRA sez sometimes you can grab some TUNGSTEN CARBIDE SCRAP
(cemented WC, not tungsten metal)
and grind it with el cheapo Harbor Freight diamond wheel / diamond grinding points / electric die grinder
to make small drills, mills, etc. on yer lathe.
You stalwarts could probably make cemented WC BULLET CORES too?
(For rotary cutting tools, you need a home made "eccentric spindle indexer"
to grind radial clearances on more than one flute cutters.)

Jay are these Tungsten cored?

They are standard cut down military surplus SS109 with whatever type of steel core was used.


Pretty irrelevant unless you want to blow your hand off.

Elite Ammunition has done a credible job on metal selection for bullets. This is not a trivial exercise.

I've worked with metallurgy in engineering for decades and what panzermk2 is not trivial. The real measure is performance and the ammunition seems to work well.

My only concern is production capacity right now.

The bullet is not solid construction, that's why Jay is concerned..
