Just got an email from LYMAN. Their new MAG-25 is soon to be shipped with a new improved mold guide with stepped rails that will permit the use of molds with different width blocks. I guess that might mean it'll be wide enough to fit N.O.E 4-5 cav and LEE 6cav blocks

I also drool in my sleep. I firmly believe that true happiness is a warm gun. Did I mention how much I HATE auto-correct on this blasted tablet.
