Hey guys. I don't own a .30-40 but I sure do have a desire to try and understand the earliest smokeless powder developments. I understand that the US Government started this with the 30-40 and selected 25 powders for tests. It would seam this started in about 1892 and maybe ended up with what we know as W-A 30, introduced to the public in 1897...as W-A 30. Sifting through what data I could fine with early powder companies, I thought I would post this generically here and see what I can learn.

I have a headache!
