Look at the Mighty Armory Decapper/Swaging die. I've got one, and so far I have not had to "adjust" it for LC or FC brass when swaging. I do have some cases that need a bit of mild reaming to complete the process but I don't find those until I'm priming the cases. I use a Hornady hand reamer for those few to clean the crimp up and move on. I use 223 for pdogs, so accurate loads but not precision accurate.
There's a guy on here that sells processed 223/556 brass and a few places that sell it which might be the way to go if you don't want the hassle of prepping it. I have never ordered it . Got the RCBS swager and always hated doing mixed cases as it will bend the rod . I only do one type of cases at a time. What's wrong with the Dillon ? Always wanted one just never spent the $100+ for it
How do you determine size of countersink, did you take case with you, would it just cover the ring to cut.

Really...you shoot Lapua in your AR's?...You keep an ammo can with a couple thousand rounds stashed for a "rainy day", all loaded with Lapua brass?
I doubt it.
I have a Dillion and found that if I wanted a uniform swage of the crimp, I needed to deburr the flash hole first. The flash hole burr can cause the support rod on the Dillion stage to bend. I also found that many of my swaged cases did not readily accept new primers.
I now use the Lyman primer reamer - in my South Bend lathe. I mount the reamer in the headstock chuck, and use a live center in the tail stock to keep the case straight as I feed the primer pocket into the reamer. I can feel when the reamer bottoms in the primer pocket and stop the cut. The next step in my case prep is to replace the primer crimp reamer with a Sinclair primer pocket reamer In the headstock chuck. Again I feed the primer pocket into the pocket reamer using the lathe’s tail stock until I can feel the pocket cutter bottoms out against the case head. These two operations produce nicely finished primer pockets that can easily be reprimed.

I just chuck the bit from my Lyman tool in my drill. Use the drill on low speed.
After having done a few...10K of cases manually swaging, I can say I prefer the Dillon Super Swager over dies for your press. With the Dillon, I can process 5x volume in same amount of time... its just that much faster with the case dropping in sideways. The drawback is it still takes physical force.... shoulder workout. Even better is to have a reloading press that also features a swaging stage, such as Dillon 1050, ect.
There is a great tool by Ballistic Tools that tests your primer pocket swaging. It's really great as setup tool for your swaging dies.

282, I know most people on this thread will laugh me off with what I'm about to say, but here it goes. I am active duty and have an endless supply of LC brass. As was said above, through it away, is silly. The brass is great, with long life that will rival Lapua brass. (Thats going to make some people mad! Lol). However, getting rid of that crimp is a big pain. I have 3 different swage tools and non of them work the greatest. After 16 yrs of dealing with this I have found that a simple deburring tool works the best. Im sure, most of the people reading this, just picked their chins up off the ground, but i have done this for several yrs with no issues what so ever. It works every time, has never affected accuracy and has never reduced the life of the brass. Trust me, I have a 260, 7mm-08, 308, 556, and 6x45 that use this brass and all of them are shooting under a half min.
I do use a prep station when prepping brass, so you might want to look into one if you like your hands.

Hornady all the way I can do them as fast as I can put them in the press eas1949 has a video of one working
All I use is this https://www.midwayusa.com/product/1012871154?pid=342199
A couple of turns and done. If I have a lot to do , take the end off and chuck it up in the drill.

this, chuck it in a drill and it takes 3 seconds per case. Cant over cut.
Yep. Me too.
For many years I used a countersink in a drill but found that the primer still hung up sometimes on the angle.
I made a swaging mandrel on my lathe that fit in a single stage press and used an old seating die to hold a home made anvil to back up the inside of the case. So nice, I get cases with a perfect .030 radius that never misses a primer.
