I've been thinking of building a double chambered for 30-30 Win. I think this would be about the perfect deer rifle here in the eastern US. Besides I think it would just be a neat cartridge to have in a double. Question is, what size action should I use? I was thinking either 20 or 28 ga. Could it even be done on a .410 size action? The 30-30 doesn't kick much at all so as long as it's around 7 pounds (which is about the weight of most lever guns in this chambering) it'll be easy to carry and it'll be light enough in recoil that a kid could shoot it. What are your thoughts?

Thanks
