The present invention is a saboted projectile with external ridges and/or an internal locking edge for muzzleloading firearms. Also, the present invention is a sabot with the ridges and/or locking edge for receiving a muzzleloading projectile. The sabot has a forward part and a rearward part. The forward part has a plurality of axial panel sections separated by narrow, axial slots. The panels have radial ridges on their outside, or external surfaces. Also, the panels have a radial ridge on their inside, or internal surfaces. The external radial ridges assist in convenient loading of the muzzleloading projectile, while still providing enough contact with the inside of rifle barrel to capture exploding gases and prevent blow-by. The internal radial ridge assists in securing the sabot to the bullet, especially when the bullet has been provided with a cooperating radial indent, cannelure or retaining ring. Consequently, when the saboted projectile of the present invention is seated in the bore in front of the power charge, the bullet will not easily separate from the sabot, and therefore, the bullet will not easily fall out of the barrel.

I claim: 1. A saboted projectile for a muzzleloading firearm, comprising: a generally cylindrical bullet with a bullet forward part and a bullet rearward part, there being a radial indent in the bullet between the forward part and the rearward part; a generally cylindrical sabot with a sabot forward part having a front edge and a sabot rearward part, there being a generally axial opening in the sabot forward part for receiving the rearward part of said bullet, so that the sabot forward part extends around said bullet rearward part; and, said sabot forward part having a plurality of axial panel sections separated by slots, said axial panel sections having an inside surface and an outside surface, and having an internal radial ridge on said inside surface, and having a plurality of external radial ridges on said outside surface; wherein said plurality of external radial ridges comprises a forwardmost external radial ridge having a greater diameter than all other of said plurality of external radial ridges so that said forwardmost external ridge protrudes radially outward farther than all other of said plurality of external radial ridges; and wherein said internal radial ridge is nearer to said forwardmost external radial ridge than to all other of said plurality of external radial ridges, wherein said internal radial ridge and said radial indent are at or near said front edge of the sabot forward part, and wherein said internal radial ridge is forced into said radial indent when the saboted projectile is pushed into the muzzle of the firearm. 2. A sabot for a muzzleloading projectile, comprising: a generally cylindrical sabot body with a sabot forward part having a front edge and a sabot rearward part, there being a generally axial opening in the sabot forward part for receiving the projectile, so that the sabot forward part is adapted to extend around said projectile; said sabot body having an outside surface, and said sabot forward part having an inside surface in the region of the generally axial opening; there being a plurality of external radial ridges on said outside surface comprising a frontmost external radial ridge having a greater diameter than any other of said plurality of external radial ridges so that said forwardmost external ridge protrudes radially outward farther than all other of said plurality of external radial ridges; there being an internal radial ridge on said inside surface; wherein both of said frontmost external radial ridge and said internal radial ridge are at or near the front edge of the sabot forward part and the internal radial ridge is nearer to said frontmost external radial ridge than to any other of said plurality of external radial ridges; and wherein, upon pushing the sabot into a muzzle of a firearm, the frontmost external radial ridge forces said internal radial ridge inward for locking into an indent in the projectile to retain the projectile in the sabot. 3. The saboted projectile of claim 1, wherein said rearward part of the sabot is a gas check having a generally axial side wall that tapers outward towards a rear end of the gas check, and wherein said frontmost external ridge diameter is greater than the diameter of the gas check axial side wall at said rear end. 4. The saboted projectile of claim 1, wherein said rearward part of the sabot is a gas check having a generally axial side wall, and the sabot has two of said external ridges between said frontmost external ridge and the gas check. 5. The saboted projectile of claim 1, wherein said internal radial ridge is rearward of said frontmost external radial ridge. 6. The sabot of claim 2, wherein said sabot rearward part is a gas check having a generally axial side wall that tapers outward toward a rear end of the gas check, and wherein said frontmost external ridge diameter is greater than the diameter of the axial side wall at said rear end. 7. The sabot of claim 2, wherein said rearward part of the sabot is a gas check having a generally axial side wall, and the sabot has two of said external ridges between said frontmost external ridge and the gas check. 8. The sabot of claim 1, wherein said internal radial ridge is rearward of said frontmost external radial ridge.
