Rifling wasn’t invented until right before the Civil War.

My bad, I took this bit to be saying that rifling was new to the scene, rather than new to industrial-scale manufacture.

No? Rifling was around muuuch longer than that, but was primarily for specialized divisions (the Kentucky Long Rifle being a notable example). It was becoming more commonly issued at the outset, but at the time, smoothbore muskets were still pretty widely issued due in part to vast stockpiles and sudden need.

McDonalds uses meat? Here I was convinced it was byproduct paper pulp.
