364: 295:) in the base of the shell. This charge fractures the matrix holding the balls in place and expels the nose of the shell to open a path for the balls, which are then propelled out of the front of the shell without rupturing the casing (which falls to earth relatively unharmed and can be retrieved and reused). These balls continue onward to the target, spreading out in a cone-shaped pattern at ground level, with most of their energy coming from the original velocity of the shell itself rather than the lesser force of the secondary charge that freed them from the shell. Since the cone of impact is relatively small, no more than 10 to 15 times the diameter of the shell, true shrapnel shells needed to be carefully sighted and judiciously used in order to maximize their impact on the enemy. 337: 160: 349: 41: 29: 325:
would ineffectually fire its contents only a few feet into the air in a cone-shaped pattern (while the casing itself remained intact). However, the reduced area of effect of shrapnel shells can be exploited, such as in the creeping barrage tactics of World War I, where shrapnel shells were able to be used much closer to friendly infantry than HE shells could.

Then fill in (with a gunpowder core) to a case of cast iron making a fragmentation bomb. When it bursts, it breaks into pieces that wound the skin and break the bones (of enemy soldiers) and blinds their eyes. 324:
One easy comparison between fragmenting HE and shrapnel shells would be to imagine a shell of each type standing stationary and base-first on the ground; a high-explosive shell would be equally lethal if detonated in this state vs. detonating on impact after being fired, whereas a shrapnel shell

that shatters the entire shell casing into many fragments that fly in all directions. The use of high explosives with a fragmenting case improves efficiency as well as propelling a larger number of fragments at a higher velocity over a much wider area (40 to 60 times the diameter of the shell),
