Making Copper Bullet Jackets: Machining Punching & Drawing Dies! Part 2

This Video:
In Part 1, I asked how much detail folks wanted to see: The answer was clear: LOTS! So let's take a step back and look at the aluminum test dies, some of their flaws, and take a closer look at how to best design the next set of dies
This Series:
Having been a long time shooter and reloader, I am undertaking my next project for my new Emco V13 lathe: Making Copper Bullet Jackets. The process steps are to blank a copper coin out of a strip of copper, cup it, then draw it in to progressively longer and thinner-walled shapes. The goal in this project is to end up with a 9MM jacket which will be about 0.6" long and 0.352" in diameter. That jacket can then be used in a swaging system (e.g. Corbin) and combined with a lead slug to make an actual bullet! 5 Reasons to Use a Fixture Plate on Your CNC Machine: bit.ly/3sNA4uH

Excellent instruction for a neophyte like me... I especially like the casual tidbit about adding a bit of taper to the punches so as to make clearance and relief so as to not allow the "worked" pieces to grab onto the punching die.

[@Kalishir]

As a mecanical engineer student, I couldn't hit the subscrib button fast enough ! You're an amazing explainer ! Only saw two of your vids till now but I loved them ! Cheers from Portugal.

[@smoothuncut]

Been a millwright all my life and what ive seen and heard from you is your one a sharp cookie! Good onyah mate.

[@Waffenschmiedinx]

I was asked to make a set of dies like this for some one and this is very helpful thank you for posting them.

[@smrettpecca]

I'm Looking forward to see another Video of you! ;)

[@LuisRivera-kd6ej]

Thank you so much for making this video series and simplifying this process. I had the hardest time trying to understand how this works from reading several books. You really helped me visualize how this process works.

[@uliseswill8488]

i dont mean to be offtopic but does someone know of a method to get back into an Instagram account? I was stupid lost my password. I would love any tips you can give me.

[@skylersalvatore2335]

@Ulises Will Instablaster ;)

[@uliseswill8488]

@Skyler Salvatore thanks for your reply. I got to the site thru google and Im waiting for the hacking stuff atm. Looks like it's gonna take quite some time so I will get back to you later with my results.

[@uliseswill8488]

@Skyler Salvatore It worked and I actually got access to my account again. I'm so happy! Thanks so much, you saved my account !

[@skylersalvatore2335]

@Ulises Will No problem :)

[@Pest789]

Process + background = good video. Thanks very much for not being afraid of detail!

[@daveb3910]

Cool project! I was actually investigating how to do this as well!

[@MOREENGINEERING]

No doubt, I expect it would complicate things. But I do believe that some form of stripper is necessary. Yes John I have had mine just over a year and very happy with it. It is a great machine. Watching your "tormach times" was instrumental in my ultimate purchase. I had originally placed my order with the "green one" but got sick of waiting (nearly 9 months) and asked for a refund. To their credit, they apologised and promptly refunded. Now Tormach, and I couldn't be happier. Great work john.

[@seleckt6600]

Many years late to this, but it was exactly what I was looking for. I wanted to create a 165gr JHP 9mm for subsonic use. Couldn't find any with those specs so I wanted to see what the viability was of turning my own. Not very viable, as it seems.

[@zenitzenit9053]

After years... How to buy these? 🤔 Or if discontinued do you offer the CAD files?

[@BulletCastDuo]

Thank you =) Yes my name is a little bit of (for now) because it is quite hard (and expensive) to get the permit to reload over here in germany. But my dad reloads ... thats where the name comes from! Have a nice day!

[@Keith_Ward]

Very work John. I would also expect all dies and punches to be polished, hardened, and some sort of die lube used during use, maybe even wax so that it is not as messy as oil. Really looking forward to following all of this.

[@Caca.R.Mattos]

Where to buy these kits? I wanted one for 9mm and 5.56

[@bobhaehn5470]

Oil in your drawing operations. Regretfully you'll have to experiment with viscosity. Thicker oils will eat up your clearance but too thin and it'll wipe right off. Norma even uses olive oil in certain operations.Also, on your cupping operation cut a recess to locate your slug concentrically. It'll make subsequent operations more uniformly consistent

[@ikocher]

This is a cool series.

[@uzomad]

One of the coolest I've ever seen on KZbin

[@Johanreistad]

In order to start check out a peddinghause punch press .With a pre annealed copper plate I make aprox 4000 discs per hrs . These discs are used in an electrical installation but looks as the ones U start with. All the best Johan

[@Johanreistad]

Hello John when I ws enjoying one of yor videos i noticed dificulties in determine the clearance and design in punch and die . I wanted U to check how the extractor normally is mounted on an excenter punch pres and also the speed which u can work with when talking excenter press. All the best Johan

[@marvinpybus4599]

A level of detail as if we were going to make our own dies to make our own jackets, please. Thank you!

[@erklaerbaer01]

you can't go too much into detail when your topic is machining ;)

[@ErwinEnterprises]

This is interesting. There is reloading info out there and there is machining info out there, but to the best of my knowledge nothing on die making for bullets. I have always wondered how they get that copper jacket on the bullet. We made another replacement splined machine shaft from 1144 today at work. The original had a worn bearing seat and the shaft had not been in service long. I can guarantee that 4340 or 5160 will work for you. I would advice caution when using 1144.

[@davidccosimeno9328]

Hey dude ur vids are so cool I am going to be a machinist when I'm older I live in ny upstate like Rome ny keep up the good work bro

[@randomstuff6690]

Very helpful video. Sir I am having g trouble to make the right calculations for the punch size and draw at each step, also the right thickness of the blank and the diameter of the black. Is there a formula for that?

[@tomharrell1954]

hi, John great video super!!! I am into reloading and bench rest shooting. I have tried many different ideas over the years. So if you want the experience, aluminum dies will not work Except for bullet molds.

[@cncshopmill]

I love long cnc videos!

[@ИгорьЯковлев-м8и]

hi!please tell me the formula (or size) how to calculate the size of a copper billet for 308 caliber bullets ?what thickness is better to take copper ? and what are the diameters of punches and matrices to use when stamping?

[@c6quad3]

looking forward to watching this series of videos!

[@michaeljohn8905]

Very Interested. I want to make full metal jacketed bullets. You are a damn genius though.

[@raymondrasco3388]

Do you have any info on making a large number of jacketed bullets quickly

[@MOREENGINEERING]

Hi John, Nice Vid once again. If I could throw in a penny's worth. My background is from the can making industry (many years ago). you mentioned at one stage in the vid that you thought that you would need to to perhaps put a taper on one of the forming dies because it would not come off the "punch". Might I suggest a taper should not work, because in providing that tapered clearance behind the front edge of the punch takes away the control of the FLOW of the material. A "stripper plate" works.

[@texasrox2010]

Can you make a die set to make bullet jackets out of pennies? I.e. to make tourist attraction bullet jackets for 50 cents.

[@farhanmanzoor3804]

your videos for making draw dies and punches are very helpful for me .i m making aluminium jakets but having problem in triming the jakets plz help me out

[@josephhornbostel9506]

What are the names of the dies and press. I am looking to purchase these? For manufacturing my own projectiles, casings and primers.

[@ronkluwe4875]

John, check your math. If you want half the weight, then you need half the surface area assuming the thickness stays the same. Half the surface area of a 1" diameter disc is a diameter of 0.707" (area = pi x radius squared). You don't want to use a 1/2" diameter to start with. Been following all your videos and appreciate you putting them up for the rest of us to view.

[@Stevensherah]

Hello do you still have the Cad Model

[@andrewdesormeau8417]

F yeah, awesome video, thank you, and GOD BLESS

[@sotdyeti]

I was just wondering if you got your steel dies perfected the way you wanted them to be?

[@krap101]

I found a video called "diy punch & die" by featony. I thought the stripper concept could be modified to help remove the draws.

[@morgan79347]

Just out of curiosity how much would a set of dies cost?

[@disonesto]

Do you sell theses?

[@Sertanejo_music23]

tenho interesse em um kit desse ,como posso compra um

[@russtuff]

Fantastic!

[@dennisbergstad9543]

Do you sell the dies

[@austin3538]

very nice job

[@loganr5783]

I want to start machining, how did you start

[@Pest789]

Yep it's an old 762-SD. That pic is a frame of the KZbin video I shot the first day I had it.

[@HanstheTraffer]

Great video. Thank you

[@robertthomassr1805]

clearance punch to die 10 percent 6 to 8 for less burr change die mat to d-2 for punch and o-1 for die a machinery hand book would help you as it has all most of the answers tables and formulas

[@eugenecbell]

How thick is the Base of the copper bullet?

[@brandonk5932]

just found your videos, very cool!!

[@gp6957]

Do you sell this..

[@123say]

bravo my regard and Happy weekend

[@Keith_Ward]

No official tool and & die experience, just trial and error with experience in machining and "making". Like you, I'm an engineer (in Ohio even) with an insatiable appetite for knowing how to make things from scratch. Not into shooting, but making is making, so I generally don't care what it is.

[@BulletCastDuo]

Not to much detail! It's awesome! Keep it up =)

[@zippy308]

Showing the prototypes and also describing your thought process is a major plus.Keep the detail, but I think you will with the positive comments.

[@2000freefuel]

you can make the projectile longer if your willing to accept your gonna have exposed lead with your existing jackets.

[@tomharrell1954]

I would love to make my own bullets but Corbins is way too expensive

[@karbravomaherdendalalbfran3123]
