I'd appreciate it if someone could explain this process to me, The only decrimper/swager that I've been able to find is from RCBS but that's fine -- I just can't visualize the process so if someone could tell me, I'd appreciate it.

The RCBS Swager uses an internal rod in the die station to support the case from the inside. The swage goes in the press ram instead of a shell holder.

At full travel, it goes into the primer pocket and swages, or displaces the crimp back into the case-head were it came from.

A sliding metal cap over the ram knocks the case of the swaging stud on the down-stroke.

If money isn't a concern I highly recommend the Dillon Super Swage 600. You just slide the case onto the guide rod and pull the handle. It is much faster and I thought easier to set up than when I was using the RCBS.

I use the case neck chamfering tool chucked into a drill press to remove the crimps from about 5,000 cases each year. It is very fast.

I've heard that the Lee chamfer tool can be used to remove the crimp. How much effort is required, and do you have to be careful not to remove too much material?

I bought a new RCBS swager a couple of months ago. The swager for 223 was not machined to final dimension and would not fit in the press ram. Plus the threads on the post that goes inside the cartridge to back up the web, were so sloppy the post that the post was tight against the side of the upper unit.

RCBS sent new parts at no cost. The new anvil fit and post was better but I still had to carefully guide the cartridge onto the post and then raise the swager into place. Made for a very slow operation for 300 pieces of brass.

Because the brass was mixed, not all of the crimp ridges were smoothed. So...I had to run that little Lee chamfer tool around every one. Thank goodness you olny have to do this once.

Couple of weeks ago, I bought a used Dillon Super Swage for $40 bucks at a gunshow. It required massive cleaning since the last owner must have smoked three packs a day and exhaled every puff on the Dillon. I then found that the eccentric had gauled and needed to be smoothed out. Took about an hour to put it back into shape. That said its a heck of a tool.

+1 Dillon Super Swage 600. Mounted mine on a piece of 2x4, then I can sit it across my legs and operate while watching the TV.

Did anybody suggest Dillon? Well worth the money I paid for mine. Great product, also does other military brass beside .223

I use the RCBS had thought about the Dillon but just haven't found a good deal on one yet.

The RCBS is good for 45acp but is a PIA for 223. After you get it down the 223 goes pretty good but you have to line the case up with a rod inside the die (that you can't see unless your standing on your head) with 45acp you can almost throw the case into the die.
