First... Smokeythecat answered your bullet-ID request, saying it is a "picket style" bullet... and the McKee-&-Mason book calls it a "Picket type for country rifle"... so I want her to get public credit for giving you its general ID. More specifically, your bullet is shown in that book as bullet #163, except yours is a smaller-caliber version of it. In particular, note that it is shown in that book's Base-type #2 section... meaning, a solid flat base which has "rounded" edges. Seeing that type of base on your bullet is what led me to its correct ID.
I should mention... a lot of folks tend to "overlook" that book's Base-type #2 section, because unlike the other base-type categories in the book, Base-type #2 does not start at the top of a page... and there are only a few bullets in the Base-type 2 category. So, guys, don't forget about that section in the McKee-&-Mason book, shown at the bottom of page 30.
Getting back to your question (quoted above)… no, it was not "crimped into a casing like a rimfire." ALL of the country-rifle bullet varieties had a paper cartridge.
> It looks as if it were made in a mold and then dropped before ever being made ready for firing?
It was made in a lead-casting mold, but it wasn't dropped. The spot on its base which looks like damage is where the casting sprue was kinda crudely removed by the guy who cast your bullet.
Now don't y'all go Democrat/Progressive Politically-Correct on me for saying "the GUY who cast your bullet."

Very-very few women ever did rifle-bullet casting, handling molten lead, until in wartime desperation the Confederate Ordnance Department employed some women to help manufacture munitions... notably, bullet-&-cartridge production in Richmond.
Sidenote: I re-worded some parts of the second paragraph in my first reply-post to you in this thread, to clarify their meaning. So, you might want to re-read that paragraph.
Lastly... my thanks go out to y'all for the recognition and praise you've given for my efforts here in the What-Is-It? forum.
