57's/157's... Glad that situation is gone. These Blue Magics are 209 size, the 57's were relegated to those hulls that had that compressed sawdust, or some such basewad that I remember.
To the OP, my Lyman manual has the Blue Magics in their own load data section, but to be truthful, and not necessarily recommended; me and everyone I shot with treated every CF hull the same; 18 grains of Red Dot and usually a AA wad. Worked plenty well enough from 16 yards for me.
