Plated shot

The pellets are sometimes graphite coated, copper plated, or nickel plated. Plated shot is normally confined to hard or extra hard shot. The alloying metal is usually antimony, and lead pellets typically contain between 0% and 6% antimony, although up to 12% antimony has been encountered. Tungsten-polymer shot is also manufactured and, as the name implies, contains tungsten metal embedded in some sort of thermoplastic.

The paints were spray applied to a number of substrates. Two coatings gave a final dry film thickness between 85 to 130 microns. For ac impedance studies the coatings were applied to shot (steel) blasted cold rolled steel plates. For interface metal-loss studies by electrical resistance the coatings were applied to 10 micron Fe foils (99.85 purity), adhesively attached by Araldite 2003 epoxy paste on one side to grit blasted glass plates.

The reactions are carried out in a 200-mL tail-form beaker, with a tightly fitting rubber stopper through which the platinum electrode leads are inserted gas inlet and outlet tubes can be inserted as required. The cathode is a platinum wire carrying a 2 X 2 cm platinum sheet. The anode is a platinum wire onto which a shot of indium is beaten to form a 1 X 1 cm plate. The electrodes are placed 1-2 cm apart in the liquid phase, which is a mixture of organic solvents. 

A steel plate ca 3/8 inch thick is used to cover the cup. The cup for noncorrosive liquids is made from galvanized 1-inch welded steel pipe 3 inches in length with a brass disk 0.0015-inch thick attached at the bottom. For corrosive liquids, the pipe is coated inside with Teflon and the bottom is Teflon tape 0.003-inch thick. It has been found that a Teflon bottom attenuates the booster shock somewhat less than does brass. The sensitivity value for a given liquid explosive is taken as the number of 10 mil cellulose acetate spacer cards required for a gap at which the liquid explosive detonates in 50% of the test shots... 

The pattern of the shot is detd by firing at a whitewashed iron plate, generally at a range of 40 yards. The marks of the shot should be fairly evenly distributed, and about 2/3 rd of the shot should be within a circle of 30 inches diameter... 

The latter may be 90° or less, as is shown in Fig. 137. The reflection of the detonation products from a barrier such as the ricochet plate involves a violent rise in temperature at this spot, due to the adiabatic compression of gases. A general view of angle shot mortar at Derne is given on Fig. 138. 

In Great Britain a test was devised for simulating the effect of blown-out shots in a shothole. Small charges of explosive were fired, from a suspended position or from a gun, in a methane-air mixture between two steel plates 2-4 in. apart in a break gallery (Fig. 140) developed by Shepherd and Grimshaw [49].
