204 Ruger capacity

[panhandle]

Have any of you 204 Ruger owners ever checked the different brands of brass for case capacity. I'm looking for the most capacity I can squeeze out of the 204 case. I had a thread about the 22-204 Ruger and I can't get it out of my head, gotta build one of these just because. Water capacity for the 223 is 28.1 grs. 222 mag is 29.8 and the 204 necked up to 22 is 32.6.
Still think this little cartridge has some potential.

If your looking for an accurate case with about the same capacity as the 204 Ruger why not go straight to the 22PPC?
