Glad you got your No. 1 action. I'd consider asking the metalsmith if you're going to end up with a pretty heavy rifle to lug around after the game you mentioned. There's still a chance here to just finish the 45-70, and order a Hagn mini action and set it up in 6.5 Grendel. With all you will end up putting in to it, the price difference will be small, but the potential may be interesting. Just fun supposing, best of luck with it.
