I have copies of some very old British manuals and standing orders and while they make references to the cartridges, they give no data regarding powder or how the cartridges were made up. Just as today, there is usually a lot of information that was expected to be common knowledge, apparently, or just as likely, covered elsewhere.
There were some interesting things to note. For instance, they used blank cartridges, which if I remember correctly, were made up with blue paper. This one publication also remarked on making up new cartridges from old, suggesting that the cartridges were not expected to have much of a shelf life.
The manuals I refer to were for cavalry. Would carbines of the same caliber as the infantry musket had a different load? Pistols also sometimes were of the same caliber and surely had a different load.
Shoot low, sheriff. They're riding Shetlands!
Underneath the starry flag, civilize 'em with a Krag,
and return us to our own beloved homes!
