Can I use .556 brass for reloading .223?

A Dillon super swage will do the trick on military brass

Another vote for the countersink in the drill press for a cheap DIY primer crimp remover. For the past 30+ years I've used an Vermont American 82 degree countersink held in a drill press to remove the primer crimps. I also have a couple different types of primer pocket swagers, but the countersink is faster and works fine. Grab a handfull of cases with the bases up and press them into the countersink one by one while supporting the case mouth with the other hand. My half deaf ears can detect a tone difference when the countersink starts cutting solid metal.

For case trimming on bulk rifle cases you can't beat a dillon type trim die with either their trim motor or a adaptor to use a router motor.

I don't think I have any equipment that can get rid of the crimped primer pockets. Any bright ideas for DIY solutions?
I do happen to have a chamfer/deburring tool and a cutting head, but no way to trim to length except by hand.

I like this for a hand powered tool also good for other case prep and I thought they were fairly priced for what you get. https://ads.midwayusa.com/product/10...20multi%20tool

I have a worlds finest trimmer for 308 and one for 223. They are fast fast fast and accurate. But they are not cheep and they take a bit of work to get them adjusted the first time. There is also the worlds cheapest trimmer. It works good and fast too. If you are going to trim thousands get one of these and power it with a drill.
I use a lathe for mine.

Rcbs makes a primer pocket swaging kit. Comes with mandrels for both large and small pockets. It is a much more precise way to remove the crimp than the hand method. You won't wind up with oversized pockets.
