5.7 Johnson and M1 Carbine

[eb in oregon]

Nothing to it. The TOK sizing die easily creates the shoulder. I use .223, 5.56 and 300AAC brass.

As mentioned when I first started working with 7.62x25 there was no new commercial boxer primed brass available that didn't include buying really expensive commercial ammunition so I formed two hundred from 5.56 brass. First shortened, then formed, inside neck reamed, resized again, then trimmed to length. A lot of work. Then about eight months later Starline started making brass and I bought a few hundred more. Much easier. While there is "nothing to it" it is labor intensive and I see no reason to make something I can buy readily. I only make stuff I can't find anywhere else (such as 5.7MMJ) as then you can spend more time shooting it than making it. I try to save the "making" part for absolute need.

Edit: It's labor intensive enough that I'd put up a large tarp to catch the brass as a CZ 52 launches cases like an Olympic javelin thrower. Losing a few cases was almost physically painful after all that work.
