awesome job Marcos!!! The dies look fantastic. Glad you went with the extra draw stage to get that longer length. Look forward to seeing some pics.

I had a quick look at Hornady .452 gas check prices on Brownells website, per 1000 ($54.99) they are half the price of j4 and corbins .224 jackets. I think the idea has some merit. The base thickness...

Final checks of the .308 jackets include concentricity and length. I am still using my original concentricity gauge which gives me a pretty good idea if the jackets are to my tolerances (less than...

Finally got my pinch die and punch back from heat treatment. Spent Sunday afternoon lapping the die to size. Also ordered some shim washers to allow for setting the height of the die for different...

Marcos, glad to hear you have a plentiful supply of 9mm brass. If you use copper strip be prepared for a bit of a price shock. And yes, we got a new PM. A bit more to the center than Adern in NZ. For...

Hi Marcos, good to hear from you. Yes 2 draws off a .75 disc is no problems. If you are trying to get a .353 jacket in one draw (cup only) you could try 5/8" or 16mm disc. This would give you a short...

Thanks plus1hcp, I'll have a few more pics soon when I trim up some new .308 jackets

Attached are pics of the 0.75 blank disc next to the 1". The cup is 0.40" diameter and then second draw is .305". I included a reduced length .261 jacket but I plan to go straight to 6mm (.240"...

Hi fc60...yep, I left out a zero! Thanks for that. I'm continually jumping from metric to imperial. It always catches me out.

Hi ebb, I'm using C12200 copper 0.70mm (.275") thick, fully annealed for both the 1" and .75" discs.

I haven't posted for a while as I'm still waiting patiently for my .264"swaging dies. In the meantime, I've been working on a batch .308 jackets. I decided to add a few calibers to my tooling as I...

Attached are images of the cup and first draw dies that will be ok for pistol jackets

Hi Mfg,

Its good to hear from another jacket maker. I think I can help you on a couple of your questions. My drawing dies are for rifle but the first draw jacket after cup is approx .400 and...

Close up of the dies. Thread is a M25x1.5 and 2mm cone shoulder. This allows the die to center in the die plate eliminating alignment error

Hi TrxR, It is really hard to get them as accurate as J4 or Hynes. My goal was to get a jacket as accurate as possible with a modest budget and resources. I'm really surprised that I have gotten this...

Some pics of the .264 jacket being drawn then trimmed.

I finished lapping the final .264 draw die over the weekend. Happy with .26080" as the finished diameter. Just a fraction under .261". Not only did I run a batch of jackets through but also used the...

Thanks M.A.D and MrWolf. I had a look at the acrolaps website...nice product. Do you know if there is an agent here in Australia? A couple of barrel laps near .300 and .260 would be handy.

Hi Firefly, yes the 2 ton press works just fine. I added a 2 foot bar instead the one supplied. All the force needed for cupping to final draw. The blanking though requires either higher tonnage or a...

Just got my 2nd and 3rd draw dies back from heat treatment. They are also 4140 nitrided to 60HRC. They have been machined undersized so I've been lapping the 2nd draw die to size. This die can also...

Here are some of my die drawings as a reference

Hi ShaneJ45. I can assure you that there is no place to go to learn about jacket making. Read as much as you can online on deep drawing especially copper alloys. But first create in your head a...

I'm using 1 inch discs 0.027 thick C12200 copper. To give you an idea of the required tonnage, I used an online calculator to work out tonnage required for a flat faced punch and a punch with shear...

Hi Traffer, I'm just out to concentrate on one thing...making a .264 bullet for my favorite rifle. I've read a fair bit on deep drawing but always happy to find out more...thanks for the link.
