'No such thing as corrosive smokeless piwder.'

Wrong. Read my post.

Smokeless powder in its infancy tried LOTS of chemicals that are no longer used, some of which WERE hygroscopic, and thus corrosive.

With black powder loads, the bullet base was touching the powder. It couldn't move.

Smokeless powder occupied a lot less of of the case, so bullet setback in tubular magazines became an issue, especially with jacketed bullets.
