Also found the reason for the rocking, I had used a fly cutter on the mill to face one side of the base. Apparently the mill spindle wasn't indicated properly to the table and it didn't make a flat cut. A few strokes across some 150 grit on the surface plate trued everything up. Still a slight "rock", but much better than before. So I chucked up a piece of 1/4 brass just to see how it worked. Way to much deflection even with only about 2" protruding from the chuck.
Looks like I'll be persuing Teddyblu's method and trying to set up some type of grinder. The radius cutter would possibly work with larger calibers for cutting ogives, but I think that .224 is beyond it's limits. At least I can replace all those plastic knobs on my lathe and mills.
