Lead bullet being supported by a wooden cup sabot in a Delvigne gun.
Delvigne further developed cylindro-spherical (left) and cylindro-conical bullets (middle), which received the bullet grooves developed by Tamisier for stability
Series of individual 1/1,000,000 second exposures showing shotgun firing shot and expanding cup sabot separation.
Before Tamisier's invention, the orientation of a cylindro-conical bullet tended to remain along its inertial axis, progressively setting it against its trajectory and increasingly meeting air resistance, which rendered the bullet's movement erratic
