Well, Dave, from what you contend in your first point, any round structured with a light weight nose would be less stable and prone to tumble. Yet Observation rounds (like the Brit L11A1 and L11A2, among others) were designed for great accuracy at long range ie very stable in flight, in order to maintain a pseudo-ballistic match to larger calibre projectiles for sighting purposes. These were typically structured with a light weight flash mixture contained within the nose, and a lead slug behind. Same goes for several US 'flash-spotting' rounds and training rounds, and numerous other specialist rounds with various mixtures housed within the tip of the bullet.
Sure, I don't know of another Ball round structured the way the Mk.VII .303 either, but there are plenty of examples of very stable specialist rounds structured that way.
