An ancient thread, but the problem remains. I am limited to shooting LH bolt rifles and this has been a problem all my life. However, I have managed to collect a number of fairly good LH bolt guns. They are usually hard to find. After years of seeking out LH rifles I currently I have:
LH Remington 700 in 22/250
LH Dakota 76 in .257 Roberts
LH Winchester Model 70 in 7 X 57
LH Mathieu in 7mm Remington Magnum
LH Ruger M77 mrk II in 30-'06
LH Granite Mountain in .404 Jeffery
The most affordable is the Ruger M77 mrk II. I would consider buying one and converting it to something like a .400 H&H or .404J for an african rifle and the tab would be less than most of the rifles that are (occasionally) available.
