The advantage is the pressure of the burning powder expands the 'skirt' of the hollow base which both seals off the gasses behind the bullet AND fits the bullet perfectly to the internal bore dimensions. BP cartridge loading that disputes the 'air gap' issue? There is a possible complication, though, when firing a gun in space. As the pressure continues to build, the case is forced so tightly against the chamber wall that it cannot move, but since we had a gap between the base of the cartridge case and the face of bolt or breech blockwhat we termed a little headspacethe case itself must stretch in the head region circled [Fig. It also stops the bullet from passing through its target, be it a deer or a person.

And how fast or slow a particular barrel is from gun to gun will make a difference as well. Air space in muzzle loaders is dangerous. I have also read somewhere that filler (wool for Martini -Henry) was used to prevent the BP breaking down into smaller kernel size during transport thereby changing the burn rate . By the way, ringing is a cumulative effect and many shots are normally required before a ring becomes apparent. Bumped bullets were .3093" into a .3090" throat. Now I use 65gn, vibrate the charged cases and use a compression die. Why are black powder guns considered firearms? Right.
