Case forming 7.65 Argentine from 30-06. Which die works?

[mrappe]

Good News:
I recieved the Lyman die set that I ordered in 7.65 Argentine and tried a case with it after using the RCBS case forming/trim die and trimming the case. I loaded the brass with a bullet using the Lyman seating die and it chambered and extracted easily. It looks like I will not need to turn or ream the case neck after all.

The RCBS trim dies are .010 larger in the neck than the RCBS FL die. If your brass is thick enough sometimes the trim die can be used as a FL sizer and will not work the brass so much. You may not need the expander but you would have to decap with a hand tool.

He's right. If you were having trouble I'd bet it's because you didn't properly full length size after the trim die. I just went back to post #1 and see that you call a trim die a case forming die. It ain't. It's a trim die. Then the Lee die after only compounded the problem. No wonder it wouldn't fit. Glad you have it sorted out now.

And if you don't have a proper heavy-duty press to form them with ( at the time my little Lyman Spartan C wasn't up to it) use a vice. Lube the case insert it into die , decapping rod removed, slip shell holder on case rim as a stop, then slowly close the vice jaws, making sure everythings lined up , Of course you have to use a rod and mallet to drive the case out of the die .
I once formed 7 X 57 cases out of 30-06....I was young and had thousands of once fired military cases. Still not a great idea.

Exactly.

One case worked in the Lyman Die but the case was not going al of the way into it. The next case got stuck in the die and when I tried to lower the ram the case rim sheared off. I had to dig the case out and the expander's threaded rod got bent. It looks like I will need to turn the outside of the neck to get it to work. I ordered a Forester hand held neck turning tool since they were the only one that I could find with a 311 mandrel for.

A classic example of not enough case lube...there's a removal tool for that to make it easy.

Yep. Can't be stingy with the lube when forming cases, or so I learned. The hard way.

Or, you could make your own.

[browningautorifle]

Yup, it's almost spot on for the factory...truth be told, you seem to need the tool every other session until you buy it. Then you almost never need it. Like twice in 20 years...

Yep! It's a bit like the various "extensions" of "Murphy's Law":

1. If you can't find something you KNOW you have, go and buy another one. The original will be staring you in the face when you get back from the store.

2. Incoming "friendly fire" is more accurate than incoming enemy fire.

3. "Quick-release" mechanisms won't.

4. Always remember: "Murphy was an optimist".

And a few "variations":

Law of Selective Gravity: An object will fall so as to do the most damage.

Jennings' Corollary to the Law of Selective Gravity: The chance of the bread falling with the butter side down is directly proportional to the value of the carpet.

Wyszkowski's Second Law: Anything can be made to work if you fiddle with it long enough.

Sattinger's Law It works better if you plug it in.

Lowery's Law: If it jams - force it. If it breaks, it needed replacing anyway.

Schmidt's Law: If you mess with a thing long enough, it'll break.

Anthony's Law of Force: Don't force it - get a bigger hammer.

Cahn's Axiom: When all else fails, get the instructions out of the bin and read them.
