quick results on sectioning those cases!
It looks like your .223 case has had its flash hole uniformed. I'm sure the .357 max cases could use that.
Its hard to say about the radius, its not that much of a difference but could make a difference. The one thing to notice is that the wall thickness increases before it gets to the radius. Did you measure both just above the radius?
That .0005" wall thickness wouldn't make any difference I'm sure, but the case head thickness might be a problem. I seem to recall that federal .223 brass had a case head thickness of around .050". You could section a few different common brands, RP, LC, Federal, and FC(yes, FC and Federal might be different, .223 vs 5.56).
One more thing to measure: the primer pocket depth. I seem to recall that pistol primers aren't as long as rifle primers. I'm not 100% sure this is true.
Regarding case length and reamers. I am pretty sure that the clymer 300/221 reamer is made for a 1.4" case length(from their old print anyway that they use to have up). Are all other outer dims the same?
