Wow, I last posted on this thread nearly a year and a half ago! Unfortunately I've given up on Ruger and the other domestic manufacturers ever making left-handed bolt rifles that aren't the usual 270, 30-06, 7mag (although they're great, I'm just bored with them). I understand Ruger is in the business of making money but why does Tikka, for example, make 6.5 Swedes, among others, for lefties? Maybe Tikka doesn't make any $.
I do think Ruger could do at least OK with a 480 in a bisley/SBH. Judging by this thread and discussions I've had at my gun club I think they might sell a lot of them. A #3 in 480 would be interesting too.
While Ruger did make a side by side shotgun, I think a double rifle is some seriously wishful thinking. But that would be awesome, especially in 470 NE. I don't think even Ruger could sell that for less than $3000.
