I came across an article on the internet claiming that the 1842 Springfield Musket had a 24 MOA accuracy, and the author of the article suggested, "It was probably a patched ball." However, the article lacked any credible sources or evidence. It appears that the author may have drawn this conclusion based on their bias toward the accuracy of flintlock muskets. What are your thoughts on this matter? Do you also believe that it must be a patched ball, or do you think achieving this accuracy is possible with a regular paper cartridge?
