You're welcome!
Of course, the other side of all this is there apparently isn't much more demand for the .338 RCM than there was for .338-06's when first A-Square and Weatherby offered .338-06 factory rifles--probably because both .33's are sort of "tweener" rounds, not offering the sort of long-range ballistics many shooters want these days, or the bullet weight and caliber of even larger rounds. No doubt some of this is due to advances in bullet construction, making heavier bullets less necessary for deep penetration.
All .33 caliber rifle cartridges, whether British or American, were essentially a product of cup-and-core bullets. A .33 bullet weighing 250-300 grains at moderate velocities penetrated deeper and more reliably than 180-grain cup-and-cores from .300 magnums. But with today's bullets we don't really need to use a 250+ grain bullet to ensure performance on heavier game.
