RCM cases are the same head size as belted cases, but the case itself is the diameter of the belt, rather than the smaller belted (H&H-style) cases. So building a 6.5 or 7 mm RCM would be dead simple in any short action set up for a .350 Rem, et al. Dennis

Well, I guess that blows my theory...
Evidently, the gunsmith who told me that was wrong....
That being said, What is the difference between the RCM case and the SAUM case?
