Once-fired LC 5.56 is what I use in most of my 223-based wildcats. MDWS got me started doing that. It takes a little more effort to match up a set of cases but once you do it's good stuff. A few years ago I went through and swagged/ resized 500 pieces, I'm still working through that batch. Basically like working with new brass - I turn to what neck thickness I need, mandrel up or resize down, good to go.
Redding sells trim dies that you can use to move cases in smaller increments to reform allowing you to make 22-250 out of a bunch of options, including other cases Lapua is still currently making.
It's a really good option to have, too. If a factory barrel has too much clearance around the neck you can use 308 Win brass to make a thicker-necked 22-250 and turn down to what you need. Involves a neck reamer also due to change in the neck/shoulder junction placement.
I'm at the point I wish we could get basic brass more easily. Starline makes 223 Basic but is not available currently, and Peterson IIRC used to make basic belted mag (might be from before they released 300WM long though). If I could get basic 204 Ruger, 404 Jeffrey, and 270 Win cases with no headstamp I'd be very excited. You can make basically anything from those.
