Dragunov: Thanks for the reference. There indeed is a description of a 45-70 red dot load there. 12 gr max for a "trapdoor" action. Very interesting.

Unlike A-Square, my 45-70 rifle is vintage--1880's construction. The fastest powder for which I have data in 45-70 is trail boss. 12 gr of that comes to 25,000 psi CUP. Green dot (which I have) is faster, and Red dot faster yet. Where they are relative to the supposed 28,000 psi max for TD actions is anyone's guess, but they are certainly no lower than trail boss pressures.
I myself do not even use trail boss and instead stick with H4198 which is around 14,000 psi CUP.
Thanks again, Dave
