The new Rock Crusher press from RCBS is a bit longer than the older one. I have a RC from 1968 and it does my Rigby ok, but the extra half inch in the newer ones would be real nice.

Redding has their Ultra Magnum press and that is indeed a class act. RCBS also has their AmmoMaster press and that will also do a 50 BMG without a hitch. I believe the Dillon 550B will do a Rigby as well, although I am not sure you need the capability of loading 600 rounds an hour of Rigby ammo. If you do, my hat is certainly off to you...
