Nosler 26, new cartridge

[cory]

RSAUM will outperform the Nosler 26? Not hardly. The Nosler 26 has almost 50% more powder capacity.

BUT...its a much bigger case, too. The RSAUM might have better barrel life, though.

Ok here's the stupid question of the day. Is it SAUM or RSAUM or is it essentially referring to the same chambers?

I do at least know SAUM is short action ultra magnum, I think.
