De-Priming before Sizing

[Duck Killer]

On bulk rifle brass. I deprime with a universal decaper then run through an expanding ball. Then trim and size at the same time. The brass is then polished for a few minutes to get the lube off. Then I put it in storage until I am ready to hand prime and inspect before reloading.

This. Plus I can deprime with a dedicated decapping die in a handheld while watching TV.

1. I deprime with a universal decaper
2. then run through an expanding ball.
3. Then trim and size at the same time.

5. Then I put it in storage until I am ready to hand prime and inspect before reloading.

You need to put step 2 after step 3 because it's the sizing that requires the neck to be expanded before you can seat bullets.

I also recommend you do another decapping after the last polishing to get any media out of the flash holes or primer pockets.

I use a universal depriming tool when processing once fired and range pick up military brass. This brass has the primer crimped in, and using a depriming tool just saves wear and tear on my reloading dies. After I knock the primers out I use a chamfering tool to get rid of the burr from the crimp, then run all the brass through an RCBS primer pocket swager. After that I'll size and deprime military brass in the same way as commercial brass.

I don't worry about dirty primer pockets, and I don't use a universal depriimer to keep from touching the necks, I just use it to convert once fired military brass into something that's easier to reload.

I need the neck to be rounded before running it through the dillon trimmer. I have another set of dies for actually reloading that is on a different head that has another expanding die.

I hand prime so I just remove the media with a pick.

I like to deprime prior to sizing and cleaning so i don’t get a stuck primer that slowed me down when reloading on the press.

Pushing the case into the dillon trimmer die should cause the case neck to be round.
It even takes out dents.
It won't take out an actual fold though, but then neither does the expander.
The expander just pushes the fold inside the case neck but that's a 1-in-1000+ cases problem.

You are technically correct but I added that die because I had problems and had the space. It just saves me headaches.

Why do some reloaders remove the spent primers in a separate step vs during the sizing process?

Neck sizing only or also FL sizing?

I simply re-size and deprime in one step, toss 'em in the tumbler if needed.
Simple stuff really. Been doing that since '78. Works.

Clean is nice though my wife thinks I'm a pig. I'm in the clean primer pocket camp.

I de-prime brass on a dedicated press in the garage as my first step after shooting, then wet tumble and dry. I don't use pins or care about shiny new looking brass, just want to keep the dust/crud to a minimum and outside. I do the rest of my reloading steps in the living room while my family is around so I like to keep the process clean as reasonable.

I'm in the deprime as first step camp.

Better question is do your unwash first, then lube, deprime, resize trim, wash.
Do you do lube /resize dirty brass and if so doesn't that build up crud in the die.

Or is it universal decap, wash , lube, resize trim, wash?
