I received a letter yesterday from Winchester responding to my inquiry as to the production of 307 and 356 Winchester brass. The official sender advised that Winchester has scheduled both cases and ammo for production in 2015, although ammo production dates are yet unknown.
Now since these are hunting items I would bet both are available in time for hunting sales, if at all.
Their advice to get on a dealer's order backlog was not very helpful as such a thing is unlikely in reality just now in the reloading supplies market.
Nevertheless, spread the word, write some more letters to Winchester, Cabelas, and the like, and generate demand info for their ears.
I would think we better buy big this time to provide for our shooting futures.
