I start with a gutted 223 de and then a bushing to finish. It can be done with a single bushing sizing but this makes it a tad easier. I load quite a few 223 necked down chamberings so this gives me the equivalent of a BASIC brass to work with. Of course cranking the gutted ones and what sized down ones I want through a 650 is very fast. On my turret it takes a tad longer.
If you don't want bushings I know that CH4D will make up a standard style sizing die for you also. 223 in 20 PRACTICAL out. They do one for the 6X6.8 and 22X6.8 to our specifications so the 20 PRAC is a cakewalk. I suspect that Redding can do that also. I own a set of standard style Redding 20 TACTICAL dies so it shouldn't be much of a jump for them to knock one out. I just use a 223 Type S bushing die on mine once the cases are formed up the first time with my final bushing. I use the same die for 223 and 6X45 also.
You can seat with a 223 but this leaves the neck doing all the straightening as the bullet can squirrel around as you are not giving it any side support. A 20 caliber will encase the bullet and keep everything much straighter according to my use of run out gages. Also a 20 seater would let you crimp if you so desire.
Feel free to ask away on this one anytime.
