We continue to explore the potential of these designs. Should Norma find merit, it is likely they will eventually offer BR style basic cases (short tapered sections and thin walls) in various base diameters and perhaps even a new line of factory offerings, based upon the SMc concept. Meanwhile, experimental handloaders who are sufficiently serious to consider the effort involved worthwhile can order reamers from Russ Haydon Shooter's Supply. We can provide correct reamer designs to accommodate any bore diameter, usable case capacity and bullet selection.
