Figure 22  APCBC projectiles. The reason for the use of this type of warhead and not a blast-frag is that the fragments produced by a blast-frag warhead cannot guarantee penetration of the RV's casing.

The propellant can either be blackpowder or smokeless powder in the form of cylindrical grains of various sizes. dailyinfo[25]='830261 Gunner Joseph J. H. MASTERS "B" Bty. Engaging the rifling imparts a spin on the projectile, and the spin stabilizes the projectile while it is in flight. Remembered Today: HVAP projectiles are made using a relatively light, usually aluminum, body to enclose a hardened-steel, tungsten, or depleted uranium core. I think it is likely that this shell is a 77mm German Artillery shell case, though a photo would help fully identfy it. This perception was reinforced by the successful deployment of shrapnel shells against Germany's barbed wire entanglements in the 1915 Battle of Neuve Chapelle, but the Germans thickened their barbed wire strands after that battle. Figure 19 shows a diagram and a photo of an AP shot. It prescribed the use of shrapnel for wirecutting, with HE used to scatter the posts and wire when cut. War Office, UK. Mechanical time fuzes use a clockwork mechanism to keep time. By shedding the light outer portion of the projectile, the diameter of the projectile is made smaller without a large change in mass, which translates to a larger stress on the surface of the target when the core hits it. It took until 1803 for the British artillery to adopt (albeit with great enthusiasm) the shrapnel shell (as "spherical case"). The bourrelet keeps the shell from wobbling in the gun barrel. An artillery gunner could anneal a shell casing and press it into the gears used to raise or lower the barrel of his gun, and a soldier with access to machine shops could create indented flutes using a similar technique on a metal press. THAT MAY KILL YOU. [clarification needed]. Projectiles that are not stabilized by a rotation are typically stabilized by drag. Tracers are used to observe where the projectiles are going.

For larger guns which had lower velocities, correspondingly larger balls were used so that each individual ball carried enough energy to be lethal. dailyinfo[26]=' Brigadier General Frederick Stuart DAWSON C M G, D S O and Bar, 4 times Mentioned in Despatches Instructional and Administrative Staff Union Defence Forces who died on 26/10/1920 SOUTH AFRICAN BOOK OF REMEMBRANCE South Africa' Note: The parachute that slows the descent of the illumination candle is missing. var dailyinfo=new Array(31) & FG & U in circle = inspection marks The shells deliver their load when a time fuze in the nose sets off an expelling charge that expels the submunitions from the rear of the shell. In the 1870s William Armstrong provided a design with the bursting charge in the head and the shell wall made of steel and hence much thinner than previous cast-iron shrapnel shell walls. Army Bearer Corps who died on 11/10/1920 TEHRAN MEMORIAL Iran' These casing are for recoilless weapons. Arrowhead shot are called that because the projectiles resemble an arrowhead. French 75mm shell case dated 1906 has few small need a good clean as been in shed #1. Sometimes these altered casings are marked to reflect the changes, but sometimes they are not. A rotating band is a metal or plastic band that serves to engage the rifling on the gun and trap propellant gases at the rear of the projectile.
