SU35,
Yep, the .338 RCM is one of the best-designed short-action cartridges ever developed. Instead of trying to cram as much powder room as possible into the available space, they actually designed a short .338-06 (or maybe .338-06 AI), with dufficient neck length avoid the potential bullet-seating problems with some of the other SFBM's (Short, Fat, Beltless, Magnums). The moderate ballistics also result in moderate recoil in a compact rifle.
I handloaded a .338 RCM for an assignment a couple-three years ago and was pretty impressed. But it didn't take the hunting world by storm, apparently because there aren't that many hunters who really need (or even want) that particular combination of virtues. Which is pretty much true of most cartridges that somehow end up being categorized as "woods" or "timber" cartridges, just because they're not super-zappers.
