RE: Southpaw Shooter
If you want an off the shelf LH/SS/3006 your limited to Browning A bolt SS Stalker or Ruger M77 II to my knowledge. If you can move in either caliber choice or finish you'll be able to look at models from almost all manufacturers: rem, winchester, tikka, savage, etc.
Being a south paw I feel your pain in finding suited firearms, my best advice is go to the various websites and see whats available then get to a gun shop and do some touchy feely.
Best of luck
