A muzzleloading bullet is provided with a pin at its back end for affixing a gas check thereto. Preferably, the pin is generally cylindrical in nature, and has a distal end that is larger compared to its proximal end that is attached to the body of the bullet. The pin therefore “expands” from its proximal to its distal end so that the resilient gas check may snap onto the pin for being secured to the bullet. Also, the expanding pin installed in a cylindrical central hole provides a small space or gap between the inner edge/surface of the central hole and the outer surface of the installed pin at one area or all the way around the pin near its proximal end. This gap increases the ease with which exploding gases from behind the gas check in the gun barrel enter the central hole of the gas check and exit between the pin and gas check when the gun is fired, which, in turn, deforms the gas check near the central hole and encourages the separation of the gas check from the bullet.

1.

1. A muzzleloading bullet system comprising:a bullet having a front end and a rear surface, an axial dimension between the front end and the rear surface, and a pin extending axially rearward from the rear surface;a gas check having a hole defined by a hole wall, the hole receiving said pin to temporarily connect the gas check to the bullet; andwherein the pin has a side surface distanced from the hole wall to creating an axial gap between the pin and the gas check hole wall adapted to receive gas flow upon firing of a muzzleloading gun containing the bullet system;wherein the pin is generally conical with a proximal end connected to the rear surface and a distal end away from the rear surface, wherein proximal end has a diameter and the distal end has a diameter, the proximal end diameter being smaller than the distal end diameter, and wherein the hole has an inner diameter that is smaller than the diameter of the distal end of the pin but larger than the proximal end of the pin, so that the gas check snaps around the pin when installed on the bullet; andwherein the gas check is resilient so that, upon firing, exploding gases enter the hole to flex the gas check away from the pin and flow between the gas check and the pin to reach the rear surface of the bullet. 2. A muzzleloading bullet system as in claim 1, wherein the gas check further comprises a radial portion comprising said hole defined by said hole wall and an axial skirt portion connected to the radial portion and extended rearward of the rear surface of the bullet and also extending rearward of said distal end of the pin. 3. A bullet system as in claim 1, wherein the hole is cylindrical. 4. In a muzzleloading bullet with a pin at its back end for affixing a gas check thereto, said pin extending axially rearward from the back end of the bullet, the pin having a distal end and a proximal end relative to the back end of the bullet, and the pin having an outer surface and the bullet further having a suitable resilient gas check member with a suitable-sized central hole affixed to said pin, the improvement comprising:the distal end of the pin being larger than the proximal end, so that, when said suitable resilient gas check member is provided with said suitably-sized central hole defined by a hole wall for affixing the gas check member to the pin, the central hole wall of the gas check member snaps over the pin, and a space exists between the central hole and the outer surface of the pin, the spacee being adapted to receive gas flow upon firing of a muzzleloading firearm containing the bullet system. 5. In a muzzleloading bullet as in claim 4, said gas check member comprising a radial portion comprising said central hole defined by said hole wall and an axial skirt portion connected to the radial portion and extending rearward of the back end of the bullet and also extending rearward of said distal end of the pin.
