The first die resizes only and doesn't decap, how do you work around this? Decap all brass first?

Your sizing die should have a decapping pin in it. RCBS dies size and decap at the same time

Not this set. Resize die resizes only. Second die decaps and expands mouth.

Maybe you don't have the decapping mandrel/assembly screwed down far enough? Is there a fully assembled decapping assembly in the resizing die?

Well, then you need it primed, then powder and then bullet seated..

Resizing die has no decapping mandrel. I'm thinking my set won't work. I last used it on my Rockchucker, I don't see a way to use it on the Dillon.

Pictures?? Never heard of an RCBS sizing die without a de-capper.

Sounds different from anything I have. The pistol dies I use that are set up are all Dillon but I have used RCBS pistol dies in my 550s, I cant remember any not decapping when sizing. You might try looking up the description of your dies by the part number and see if there is something different about them.

Well that set would certainly load ammo.. how are you going to charge the cases? That would come right after priming..
(I'm most familiar with the Lee 3 and 4 die sets with the powder through the expander die).

What year are they? I've never seen a set like that. It wouldn't be the first time I was wrong about something.

 

[Lilhigbee]

Thanks for posting the instructions. It makes sense once you read them, but I'm not sure how the others work then?? I'll have to do some research.

I bought then in the mid 1980's. It wouldn't kill me to sell them and get a new set. Would work fine on a single stage.

I found a set of carbide dies and they are the standard size/decap, expand, seat

That's what I need!

About $50 at Bi-Mart.

Wow, that's different... my RCBS dies are also the standard 3 die configuration in 45 acp performing sizing and decapp in I the same die.

Just a thought, but from the various folks I have talked to, it seems that the decap process is the source of much of the problems with dirt and crud fouling up the process. Maybe decap first, then put the cases through the progressive?

Thanks for everyone's help. I haven't reloaded in nearly 35 years and I though my brain was slipping. I just called RCBS. They said my set was made before they offered a progressive press. They are sending me a kit to make my resizing die take a decapper so it will perform just like the modern die sets. Free of charge.

Nice, so that sizer has internal threads.. the online cutaway pics looked like it didn't.

That's great...
You'll still need a powder thru the expander die for any progressive/turret press.
just sayin'
