Interestingly I'm looking at "The Volunteers hand book"
this has an abridgement of hardee's infantry tactics listed as "adapted to the use of the Percussion musket in squad and company exercises, manual of arms for riflemen"
it appears to be by capt j. k. lee of the first regiment of virgina volunteers. it's dated 1861.
The detail on page 30 for Loading and firing lists @ action 4. Charge-Cartridge 149: "Fix the eye on the muzzle, turn quickly the back of the righ hand towards the body, in order to discharge the powder into the barrel, raise dhte elbow to the hight of the wrist, shake the cartridge, force it into the muzzle and leave the hand reversed, the fingers extended, the thumb extended along the barrel.
it then goes into drawing and ramming the cartridge.
source for that is here: http://www.storymindmedia.com/angrya...onfederate.pdf
So it's plausible at this point that both were perhaps used? I have got the 1861 US infantry tactics one here and your quote is verbatim Thomas and spot on, considering the minie bullet and it's grooves however, I would honestly think that to be loaded without paper rather than with, and this would be regardless of whether the tallow mix was considered lubricant or anti-fouling mixture.
