A sabot for a muzzleloading firearm has a cylindrical body aligned with a bore
axis. The body has a sleeve portion extending in a first direction adapted to receive
a bullet. A post extends from the body in a second direction opposite the first
direction. The post may have a cross sectional profile that has articulated surfaces,
and which may define channels along the post. A powder pellet defining a bore may
be closely received on the post, with an interference fit retaining the pellet
on the post. The sabot may be employed to extract a pellet from a storage container,
by inserting the post in the pellet bore to extract the pellet from the container.
The sabot may be part of an assembly including a bullet and a pellet, which may
be loaded into the muzzle of a rifle as a single unit.
