Here is something I recently tried and it appears I have had some decent luck with it. I have a pile of bad 223 brass (crushed, etc) and after reading all the info on this page I decided to give swaging a try. Looking at my reloading manual I noticed that the 222 remington has a shoulder diameter of .358.
I first cut one down to around the length of a 9mm case. I didn't do any measurements since it was only an attempt. I then annealed the case and ran it thru my lee .358 push thru sizer. The next step was to fill the case with lead. Again, i did not put a ton of time into it since I was not sure it would work so I just melted a 124gr 9mm bullet and poured it into the case. I then lubed the case/bullet and pushed into the 222 die. I then knocked it out with a wooden dowel and then pushed it thru the lee sizer again. The final diameter was .360 and around 160gr which is good for my marlin 1894. And they cycled perfectly even with the wide nose.
I made 5 of these this way but forgot to take a pic before I shot them. I did save one I found in my backstop. The shooting was done at 50 yards and my rest wasn't the greatest so I think there is room to improve.
Sorry for the terrible pics - I used my phone.
