Bill: Whatever was in the barrel before you pulled the trigger and is not there about 1/220th of a second after you pulled the trigger is ejecta. Look at the illustration on p.121 of Parker Guns: Shooting Flying and notice the differing volumes of black powder, bulk wood powder, and dense nitro powder. To the extent that these powders vaporize and leave the barrel they are ejecta as much as the wads and shot, but in proportion to relative powder weight not volume. EDM
