Building a .350 Rigby, 10.75x68, and Mannlicher stocked 9,3x62 and two 6.5x55's; one on a std 98 action, the other on an intermediate.
Just completed a McMillan stocked 9,3x62.
The .350 Rigby is a terrific thumper for a medium.
I owned a Rigby Double in this cartridge and a mate had the corresponding 360 Westley Richards in a WR Double.
The 350 used standard .358 bullets and the .360 used .366 or 9,3.. caliber bullets. (I did the reloading for both)
The Rigby was the more powerful cartridge and if you choose a bolt action, (more likely option) there is a rimless version as well, for obvious reasons.
