Definition
A projectile that changes its fit during firing eases the conflict between convenient loading and effective rifling engagement in muzzleloading rifles.
Designs associated with the Minié ball developed during the 1840s and became influential in the mid-19th century. The U.S. National Park Service biography of Burton documents the Minié design around 1848 and subsequent improvements, showing that it was not a single version that remained unchanged thereafter.
These projectiles combined ease of loading with effective engagement of the rifling during firing, encouraging the use of rifled muzzleloaders. This is a projectile design, not an ignition system, and it does not automatically imply the use of a metallic cartridge case.
The Chinese term “米尼弹” (Minié ball) transliterates a personal name. This round of research has not yet verified a consistently used distinct term in Qing-dynasty documents or the history of its adoption. These questions remain on the technology family’s list for further verification.
