"In all honesty, we will probably never offer carbide dies for the 45/70. The case wall is actually tapered and would require the carbide to run the entire length of the die, which is expensive and cost prohibitive. You would still have to lubricate the cases, which also defeats the purpose."
based on that info, I'm not hopeful the answers from the other manufactures will be any different .... oh well, applying case lube ain't that big of a deal
