I added to the post so there is more information now.
The Rigby is a fine cartridge and it was designed for Cordite Powder (Sticks) that was used
then, and the case capacity was needed and pressures were low for dependability at high
temperatures found in Africa. So the cases are designed for lower pressures and are
relatively thin. newer cases are better materials but to prevent higher pressures with
traditional loads they are the same volume (Still Thin compared to modern cartridges
designed for higher pressures.
In a tight chamber and with careful loading(Not over sizing) they can last a little longer
but if hunting dangerous game you always want to full length size so there is no problems
feeding and extracting the worst time.
And as to the Lapua brass,unless you improve it (blow it out and change the shoulder angle
it has less case capacity than the RUM. I looked at the Lapua and found no real advantage
except case life and the RUM uses a standard magnum bolt face.
The reason for no muzzle break is that most PHs will not allow a break to be used on dangerous
game hunts because they are there to save your ass and don't want to be slapped up side the
head with the blast and losing concentration momentarily. It is acceptable to have a break
and replace it with a barrel nut/Thread protector.
