Which die is missing?

[gunboat]

You are missing the expand die and plug --
die #1 sizer decaps -- you seem to be missing decap pin - and sizes.
die 2 expands case -- It is a universal die shared by many calibers, only the expand plug (.356 ) is specific.
It is a inexpensive die --
die #3 is seater -- It may or may not crimp.

I don't see the carbide ring on the sizer --
It looks like you may have two seat stems, one in each die -

Hey so I did some research and just wanted to see if this makes sense.

Apparently on the SUPER OLD dies, some of them had a decapper/expander on one die, another to size, and another to seat.

That being said, I am missing the expander/decapper and am in possession of a sizer, and a seater. The followingmakes sense in my head but I wanted to see if you guys think so as well...

If I was to pick up an expander (which are inexpensive like you guys said) and a universal decapper, I could then use the decapper to pop out the primers, use my universal expander to expand, then use my existing sizing die and my existing seating die and that would complete the process?

Thanks

Your sizing die should be able to decap as well --
A photo of the sizer stem would be helpful.
And, Yes, the older dies, even pistol dies, were two die sets and the sizer die full length sized, decapped, and expanded the case.
The nut that retains the decap pin was also the sizing button.

PS -- Looking at the bottom right photo - if that is what is in the sizing die, it appears to be a seating stem.
you need a 1/4-28 decap stem, decap pin, and expanding button for that die.
Perhaps simplist is to get a newer expand die with a combo decap expand stem --

Okay here's an updated pic of what's inside these dies. From what I gather, if I buy a universal decapper and an expanding dye, I should be able to use these two dies.. for sizing and one for seating?ImageUploadedByTapatalk1363403601.319290.jpg

looks like you have 2 seating stems there. You are missing the decapiing pin for the sizing die and the decapping/ expanding pin for the expander die. I have 2 sets of those in 38spc/ 357 mag

I can't see the carbide ring either --
Indeed that is a seat screw in the sizer --
A call to rcbs may get you a 1/4-28 decap screw, .356 button and decap pin.
If you decide to just get an expander die be sure it also decaps.

yes diffenately steel dies make sure to use lube on your cases or they will get stuck
