Another potential worry for folks who just keep pouring brass, bullets and powder in to their respective bins on progressive presses, without inspecting each individual component?

Would it be possible for a 9mm bullet to end-up in a larger capacity case, UNDER the proper bullet? Probably not a 9mm under a .40 cal in a .40 S&W case, but how about a 10 mm case, or a .45 ACP case, or a .41, .44 or .45 revolver cartridge case?

If that can happen, it will probably raise pressure considerably simply by subtantially reducing powder space.
