Perhaps the answer is simply that a small amount of air space either only behind the powder itself, or over the powder and behind the projectile, or even BETWEEN the powder and the projectile, is not critical because the expanding gases quickly fills that small air space BEFORE any dangerous overpressure could occur. If so, that doesn't explain why we have always been admonished by the firearm scientists and manuals that we MUST fully seat the projectile against the powder charge in our smoke poles.

Unless they knew this and were just preaching to the lowest common sense denominator (and for liability purposes too) so that someone wouldn't foolishly load their ball only halfway down the barrel to where it WOULD become a problem since the gases had largely expanded and reached high pressure by the time they hit the projectile and thus it would act as an obstruction. Could it be that simple? If so, then the firearm scientists and firearm manuals have actually been preaching wrong to us just to make sure someone doesn't foolishly load their ball halfway down the barrel. Could that be it? Could it be that simple?
