progressive question

[snook-slayer]

I’m moving up in the reloading world, after handing down the single stage press my father gave me, I bought my first progressive. I’m gearing up and a question came to mind, When loading necked brass …. Say 223, using a full length sizer decaper in a progressive setup, when should you trim and chamfer? Before you put the casings in the progressive or do it in two stages, i.e. run them through first with just the decaper / sizer die in place and then trim and chamfer and load them back into the press to complete the process.

Or is there some thing else I’m not thinking of?

Thanks in advance.

I size all my brass on my LNL using the sizer die only. Then I prep it & hand prime prime it. Then I run it back through the LNL to load it, leaving the sizer out.

Snook-Slayer:
First of all welcome to THR Site, and secondly you have asked an excellent question. There are several different anwsers as you have surmised. I load 223's and 308's on a Dillon 550B press and have large quanities of commercial once fired brass, so I just mouth chamfer them and reload normally. After each firing I check case length and segregate the ones that need trimming. I uually run a half dozen or so "OK" cases thru my Dillon's sizer die and again check case length. If still OK I reload normally. Ones that need trimming, are run thru a universal decapping die, trimmed, chamfered and reloaded normally. I have run into a problem with a batch of LC 223 NM cases. I had to deprime, ream the primer pockets and tumble before loading. I was finding pieces of media stuck in the primer holes, so with those I chamfer, lube, size w/o removing the primer, tumble and reload with my universal decapping die in the first station. I do use my Redding single station press to do a lot of my preliminary work such as decapping. Don't worry you will work out your own system
