I'm just not sure what this cartridge brings to the table that is not already out there. Sure, it has more range than 30-30, but to me a levergun is a handy, relatively shortrange gun to begin with. There is NO WAY I'm putting a scope on one, and that seems to be the best way to maximize this new cartridge. Throwing a scope on a levergun completely takes away its handling advantage, and I might as well grab a boltgun.
If this cartridge doesn't catch on, a shooter would be in an awful predicament. They don't sell bullets for reloading, and that alone turns me off. I suppose you could use .308 or 30-30 bullets, but that would kind of defeat the purpose of the cartridge to begin with. We don't have access to the powder they use, so even if there were bullets, you couldn't access the full potential of the cartridge.
No way I would buy something I couldn't reload for, not ever. Even if I choose not to reload, I like to have that option. Most 30-30 I shoot is store bought but I know that in a pinch I could go out in the garage and load up a couple hundred.
But, hey, the more the merrier.
