No BP involved what so ever-only in the parent case of 38-50(Ballard) and 38-55.
So they(Marlin and UMC) used the name 30-30, but the second thirty represented smokeless(a stray from the normal classification) powder, not BP. Tom.
This is very correct. This was a very common practice during this time in history. It was so correct that S&W lost a government contract because of it. I am talking about the more superior handgun, the S&W Schofield. Wesson would not design his handgun to take the Colt .45 round for his gun. And the Army would stay with the .45 Colt SAA pistol. It was a shame because the break top Schofield was much more capable for reloading then the SAA and would have been much better for the mounted calvary troops.
Just thought I would throw out this small tidbit.
