I should stop reading this board. All this time, I thought the .300 RCM was a silly waste of time. But here it is...

-short-fat proportions for consistent ignition
-fits in a short action
-30-degree shoulder angle
-just a little more capacity than a .30-06

Seems like it should be an outstanding choice for putting heavier, higher-BC .30-cal projectiles right where you want them, really far away.
