The subtitle of the first Gun Gack is "The Hunter's Guide to Handloading Smokeless Rifle Cartridges," and I explain the in the introduction why I didn't include the .45-70: There are so many rifle variations, including old black-powder "trapdoors" and modern single-shots, that publishing data suitable for all becomes pretty complicated. Especially because of the present trend toward poor reading comprehension, and suing people who publish loading data when a smokeless load damages a blackpowder gun--or the shooter.
But I did include some black powder (and suitable smokeless) data for the .38-55 in Gun Gack II, and may include more in GG III, including the .45-70--and the .50-70, since I just bought an original Allin conversion trapdoor made in 1866. Still haven't made up my mind.
