Gas check with system for improved loading and retention in bore of muzzleloading firearms
First Claim
1. A gas check and muzzle loading bullet combination, wherein:
- the bullet has a side surface and a rear end surface from which a bullet post extends rearwardly;
the gas check has an external side wall, and a front surface with an aperture for receiving the bullet post, wherein said aperture is defined by an internal side wall;
wherein the external side wall is an outer wall of a rearwardly-extending skirt of the gas check, and the skirt has an inner axial surface comprising axial grooves;
wherein the external side wall of the gas check has at least one ridge and at least one adjacent recess, wherein the at least one ridge is adapted to contact a bore of a muzzle loading firearm and the at least one recess is adapted to not contact said bore; and
wherein no part of the gas check extends along said bullet side surface.

Abstract
A muzzle loading bullet gas check has external recess and ridge system, and/or an internal locking ridge system. The preferred gas check has an opening or recess on its front end for receiving and frictionally engaging a rearwardly extending post of the bullet, the opening also preferably including an internal radial ridge for gripping the post and/or locking with an indent on the post. The barrel-interacting part of the gas check has one or more external recesses and adjacent radial ridges/edges protruding relative to the recesses, which serves to reduce the total surface area of the gas check contacting the bore. The recesses do not touch the bore of the firearm, resulting in less friction and easier loading, while the outer ends/surfaces of the ridges/edges do touch the bore to retain the bullet in the bore during handling and hunting and to effectively capture gasses after the firing explosion.

6. A gas check for connection to a muzzle loading bullet, the gas check comprising:
-
a radial front wall having an aperture defined by an internal side wall; a skirt extending axially from said radial front wall and having an external axial wall and an interior axial wall, wherein the interior axial wall surrounds and defines a cup-shaped space for capturing gasses from a muzzle loading firearm powder explosion; wherein the external axial wall comprises a plurality of circumferential recesses and at least one ridge between said recesses; and wherein said interior axial wall comprises axial grooves adapted to weaken the skirt. - View Dependent Claims (7, 8, 9)

10. A gas check and bullet combination for a muzzle loading firearm having a barrel with a bore surface, the gas check comprising:
-
a radial front wall having an aperture defined by an internal side wall; a skirt extending axially from said radial front wall and having an external axial wall and an interior axial wall, wherein the interior axial wall surrounds and defines a cup-shaped space for capturing gasses from a muzzle loading firearm powder explosion; wherein the external axial wall comprises a plurality of circumferential recesses and at least one ridge between said recesses; and wherein said interior axial wall comprises axial grooves adapted to weaken the skirt; and wherein said circumferential recesses are adapted to not contact said bore surface, and said at least one ridge is adapted to contact said bore surface, so that total surface that contacts the bore surface is limited for easier loading of the gas check and bullet combination into the barrel and so that said at least one ridge seals against the bore surface for capturing explosion gasses. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
