Does anybody here actually stamp "coins" out of sheet copper and then....??

[Russel Nash]

Hi all,

Yeah, just curious if anyone here actually buys really thin sheet copper and then stamps out little circular disks called "coins" and then forms their jackets that way???

Thanks!

[docone31]

If someone does, it will be fascinating.
I once saw an article where, if I believe right, there were six steps in making "coins" into jackets a core could be put into.
A very precise process.
I would love to see it done.
I have been wondering about casting into copper tubing, then swaging into a shape.

I don't but a buddy of mine is getting the equipment set up to do just that. He has some of the equipment (presses I think)but is waiting on the dies and punches and probably some other stuff, which he hopes to have by spring. He is going to make .30 cal bullets to start off with and then others as he sees fit.

Way back when...I stumbled across the bulletsmith's forum and saw all these neat pics that people took of their set ups.

Man! I wish I had done the right click save thing, and saved all those pics to my computer's hard drive.

Alas...the bulletsmith's forum disappeared. :|

For whatever it is worth, I was at a Lowe's store the other night and I looked at their flashing materials.

They had 3 ounce copper on a roll. They also had aluminum step flashing.

Then I thought back to some of Boerrancher's posts and maybe a few others here.

Boerrancher was using the aluminum from the Bud Lite bottles to make gas checks.

I was thinking that would be funny as heck to see the Bud Lite "label" on a bullet.

If you can track down a copy of "Ammunition Making" by George Frost , It was an NRA book...

They have several good dimensioned drawings on making cups, among other things of interest

Got a link? That book is on amazon ISBN 0-935998-57-8 and is available but for close to $200..............

You would have to be pretty serious to make real jackets. Just to give you an idea of the pressure involved, the presses used by Nosler to make their bullets start at fifty tons. In order to make their big bore bullets, when they quit turning the jackets on screw machines, they went to a one hundred ton press.

I would be very interested in seeing how someone could make their own drawn jackets.

Thanks hardcase, welcome to the site ;)

You don't need 50 or 100 ton presses to make a good bullet or jackets.
This will make a good bullet and jacket.

This is what these presses make with no effort from that sheet of copper flashing there laying on.
.224, .308's, .38's .44 and 458's.
I cant show you the dies anymore because I been selling off the jacket making dies because I quit shooting high power.
I have several 1000 .44 & .45 for the .44 mag and .444 Marlin to last me for the rest of my shooting days.
If any of you are thinking of rolling your own you better get a pencil out and do a lot of figuring to see what the pay back will be.
This equipment has gotten to high priced over the 40 some years I been at this.

That is the thing.
Cost.
If one could make one better than the commercials, might be worth it economically.
I will read everything I can see, and stick to casting and paper patching. When I need jacketeds, I can always buy one hundred or so.
Don't know why I would though.
Paper does it better.

[ANeat]

For me Im going to try and do my own dies. Not so much about saving any money over factory stuff but I just want to see if I can do it.

I would be money ahead if I just gave up shooting all together but that wouldnt be any fun.....

Its a "hobby" right ;)

[elk hunter]

Leadpot;

How thick is the copper sheet you're using?

Are you pinch trimming to length or using some sort of rotary trimmer?

How many steps/dies are you using?

I would be very interested in your process especially if you are make a truly commercial hunting or target quality jacket.

Commercial cup and draw jackets are made from quite thick material in order to get a tapered jacket that is thick at the base and thin at the nose. My experience has been that is difficult to maintain uniform jacket wall thickness so that center of form and center of mass are the same.

[Lead pot]

elk hunter.

The copper flashing I used was .020 and with the cups made from that I pinched trimmed them because of the difficulty to hold them cutting them with a rotary trimmer I made from a chain saw sharpener.
My hunting bullets for the .444 and .45-70 I used copper tubing from type M to type K and that I cut with the saw.
The cores I core bonded then with the alloy of pure lead to 1/16 L/T depending on the intend target or hunting. 1/30 alloy was good for what ever.
If you want a good even fill with out voids and a core that stays put bond (solder) it to the jacket! The dies I used will be better to point you to the Corbin site, there is everything you need and he explains it better than I would with illustrations.
Like I said above I been selling my equipment because I don't shoot the disciplines I used to and no longer need the expensive dies laying around not being used.
But I'm keeping the presses and some of the large caliber swage dies for the .40 and .45's and the .308's I'm keeping for now but the .264, 224 went with the jacket making dies.

I posted this link a few months back for someone on this site....check it out.All this machinery was homemade - a lot from scavenged material. Scroll down page till you see The Bullet Factory Pics and enter http://people.aapt.net.au/~nelltash5/bullet%20factory%2002/index.htmer .Hope this is helpful. Regards Peter

Try this on.......should work..............worth checking out

[peterthevet]

Sorry link changes after I have cut and pasted it here.....last try

Post above I typed in the whole link manually but it still changed after I was completed typing it........not sure what is going on. Google search The Bullet Factory (australia) and see if it comes up!!

Final try

[peterthevet]

Success!!!!! Shows forming .458 jackets from flat disc.

[ANeat]

Those guys got some slick setups. I like their knurling tool

[coyote]

All my jackets are made from copper sheet and some brass sheet .027" I coin ,cup ,1st draw 2nd draw and final draw then trim in a pinch die I do .224 6mm and .308 with a press I made that is similar in design to the corbin mega mite .
All the dies and punches I made myself it doesn't take as much pressure as one might think a lot has to do with the shape of the bell mouth on the die and good lube the material flows and you can feel it.

[ANeat]

Welcome Coyote. Im sure everyone would like to hear more details on your setup.

Hi all,

Yeah, just curious if anyone here actually buys really thin sheet copper and then stamps out little circular disks called "coins" and then forms their jackets that way???
