I’ve been trying to research as to why load books stopped listing 2400 for the 45-70 Government. The Lyman Reloading Handbook #44 has several loads... then poof! Nothing.
I had read that Alliant was going to do some more current pressure testing, but couldn’t find any data on that testing or why 45-70 loads with 2400 stopped being published. I could only find one individual who had a poor burn and had to dig out a molten clump of powder from his rifle.
I know several folks are still using it in the 45-70...
Just wondering if anyone has a definitive explanation or just hearsay, which seems to be all I can find.
