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.

Just one of the multiple reasons I'd like to build a 6.5 RCM one of these days... grin.
