I had been waiting to get one of these for my Hornady progressive before processing a substancial amount of .223 brass I had decapped and cleaned. Here is the unit in action for those not familiar.

Now that I have swaged about 4000 (almost halfway thru what I have cleaned) I can say its way better than the other methods I have used which are the Dillon Super swager and the RCBS version.
Not saying go buy a Progressive Hornady BUT if you are like me and have one its a good addition.

I have the RCBS and like it.

That's pretty slick.

I havn't looked into my options using a Co-Ax.

You don't even work up a sweat with that, pretty nice

Exactly.. I have the RCBS on my garage bench but that thing gets old quick. The Dillon is easier on the hands than the RCBS but this method is way easier and faster. Another thing I have noticed is that with both the Dillon and the RCBS I would get a few that I had to go back and swage again to get the primer to go in. So far not a single one with this setup.
The only issue I have had is if you get a piece with a dented neck it won't slide down the spindle and falls on the floor. I just keep a 223 die in my Forster press adjacent to the Hornady so I bump the brass into it to round out the neck and keep going.
