I've seen this done, and the last time I saw a fellow doing it I asked him, "Did that patched ball offend you in some way?" :youcrazy:
The following is From: The Muzzle-Loading Cap Lock Rifle by Ned Roberts, 1940 p. 103
Italics appear as they do in the actual text
"..., and having filled the charger even full from the powder horn, pour the charge carefully into the barrel; then place an oiled linen, or other cloth, patch over the muzzle being careful to center it over the bore. Next place a round ball, with the sprue up, in the center of the patch- be sure the ball is truly centered in the patch- press the ball down with the thumb even with the muzzle,...., Do not ram, or pound, the ball down the bore, and do not "whang" the ball with the ramrod onto the powder - simply seat the ball firmly on the powder with a light pressure on the ramrod. ...., and ramming or pounding the ball down the bore will upset it making it merely a slug of lead instead of a sphere and thus destroy all accuracy.
Be careful to seat the ball on the powder with uniform pressure each and every time, because if you seat it very lightly one time and very hard the next, these two balls will have quite different points of impact on the target."
