Ill post info for others who might try this. I made a reamer and started cutting brass. I do not like it. I anneal it, ream it, yet it still is thick. Have to watch your loads because the case volume is less. And the rim of the 223 is a tad smaller than the Tok. It pops out of my primer press, making I a booger to prime. It also jumps out of my case sizer. I just bought some Starling brass from Midway and it works great. I wanted to try the 223 to see how it works. It will work, but I do not like working with it or the results.
