Bottle Necked Cartridge-Will a rifle using a bottle-necked cartridge shoot harder than one of the same caliber and load, in a straight shell?
In black powder cartridges the shape of the shell makes no difference in smokeless cartridges, as regards power, but smokeless rifle powder requires a large air space in which to burn, or it will cause extreme and dangerous pressure. You will notice that the powder charge in a high power rifle cartridge in a high power rifle cartridge occupies only a small portion of the space allotted to it, and by shaking the shell you can hear the powder shifting. To get this air space in a small caliber cartridge, the shell is enlarged behind the bullet portion, and this makes it unnecessary to lengthen the shell, which would have to be done otherwise.
