In Spencer Wolfs book on loading the .45-70 for the Trapdoor Springfield, compress meant compress.
If I put 70 grains in my case, it almost fills the case. I use a compression die to push the powder down almost a half an inch, thus making it into a solid pellet, in order to seat the big old Govt 500 grain bullet over a card. The thing you get into with the original loads of compressed black powder are the primer flashhole sizes were larger than today, and the primers used then were roughly equivalent to magnum primers used today. If you mess with one factor, you create a chain of factors that need to be addressed.
