I'm pretty sure that the RUM is a round nose soft point.

I called Hornady and they said the case head diameter is the standard belted magnum diameter of .532".

BBJ, Hornady said the guns and ammo for it should be hitting stores early first quarter 2007. Of course that will vary by stores and region I would assume.

Another real benefit of this cartridge is that anyone with an extra300 win mag, 7mm Rem mag, etc... laying aroundand contemplating a .375 should be able to simply change out a barrel with no other modifications needed. Very inexpensive.
