Well, looks like Federal is on-board... I'm willing to bet they're devoting a pretty good part of their output to getting the new caliber to market. I doubt S&W would be announcing a new gun without guarantees from Federal that they will keep up their end.
I agree with this. I don't think Smith would make the guns unless Federal committed to a certain amount of production.
If the new cartridge is going to make it, it is going to have to be readily available
