So, the top contenders, if I'm reading the room right, Are Tikka and Ruger.
I'd put in on a Tikka roughtech in 6.5PRC. If it is already cataloged, then there isn't much point unless this is the way we get them actually imported.
Also be in on a Ruger African in, as stated before, something available that kills deer. I'm pretty easy here as long as I can feed it.
As an aside, I know that both Winchester and Kimber have produced LH actions in the past but don't think they have any plans to do that again.
