Shot cups

Sometimes a plastic buffer material (usually white granulated polyethylene) is mixed with the shot to help prevent distortion during discharge. The buffer material may be found in the wound channel in close range shootings. Another innovation to prevent distortion is the use of a shot cup that encloses the shot as it travels through the barrel, with the shot cup falling away when it exits the muzzle. 

A shotgun barrel is made in one section, but it is described as four, each with a different function. The shotshell is seated in the chamber which is physically connected to the forcing cone and the bore. When you pull the trigger and the shell s powder ignites, the shot cup (also called a wad) and the shot are shoved out of the hull and into the forcing cone. 

Should you choose to shoot steel in an older gun, carefully consider the load s chamber pressure and opt for a lower pressure load. If you hand load, consider adding a buffer or a Mylar wrap inside the shot cup or perhaps dropping down in shot size, if possible. The objective is to keep steel pellets from coming into abrasive contact with the barrel as the burning gas propels it forward at a thousand miles per hour. 

Gamebore s steel lines begin with seven competition loads that are available only in 12-gauge, 2 M-inch shells with plastic wads/shot cups except one 1 Vi in the Super Steel line. The new 3-inch Silver Steel load of plated 4 or 5 for pheasants or upland birds uses fully degradable components a powder card, driving wad and fiber shot cup. 

Gamebore believes that tungsten matrix is the best-all-around shooting alternative to lead because its formulation can be very close in density 11.0 gm/cm to 10.8 gm/cml The matrix is pure tungsten powder mixed into a polymer (essentially, a plastic glue). Gamebore s formulation is designed, the company says, for uniform size, consistent density and maximum muzzle velocities because it is malleable, it is safe for most older barrels. These shells also use a fiber shot cup which decomposes easily. 

Bounce happens very rapidly, but that does not mean the impact on shot inside the shell column is negligible. Because a rapidly expanding gas pressure wave is more explosive with steel than with lead, effective wads for steel loads tend to be thicker. This protects the barrel from scarring because the rule of columnar loading says that force is exerted toward the sides - into the shot cup and through the slits in its sides - as well as forward toward the barrel. (Examine the inside of a spent wad and you will see a similar result, even in a light lead load). 

Especially with older shotguns and older chokes, steel shot has required use of specialty reloading components, such as shot cups or wads that fully encapsulate the hard pellets. (Photo Ballistic Products)... 

Probably the closest you ll get to a recipe for a classic Jell-O shot (no, it s not on the box) is Ray Foley s Ultimate Little Shooter Book II, which calls for a cup of liquor to a packet of powdered Jell-O, a Kraft Foods product. Most of the books skip it, leaping from the Jack Rose to the julep. 

Add about 10 g of copper shot to the cup and find the mass again. 

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... 

A model of possible terrorist attack (single shot at metal-concrete container from grenade cup discharge at on-shore site of Atomflof , Mmmansk Shipping Company) was presented in the 2002 NATO-Russia Advanced Research Workshop Remaining Issues in the Decommissioning of Nuclear Powered Vessels [2]. According to the model, even such - not very powerfiil - hypothetical terrorist impact could lead to serious implications for personnel and environment. 

This is an elegant dessert idea for entertaining. Serve each person a plate on which you place a small bowl of fresh, rinsed raspberries (they re best when they re in season), a shot glass of Chambord raspberry liqueur, and a toothpick. Use the toothpick to pierce and pick up a raspberry to dip as a cup into the liqueur. You ll get raves for this no-effort presentation. 

One is contained in all the cups of tea, coffee, and cocoa which we consume. All of these beverages contain the stimulant caffeine. Whenever you take a cup of coffee, you are a drug user. We could go further. Whenever you crave a cup of coffee, you are a drug addict. Even kids are not immune. They get their caffeine shot from coke or pepsi. Whether you like it or not, caffeine is a drug. When you take it, you experience a change of mood or feeling. 

Thomas sits in an overstuffed armchair. (The next sequence of shots will be done as we dolly behind Thomas s head.) He raises a cup of cider to his lips. Drinks. Lowers the cup. 

An average 8 oz cup of coffee contains 75 to 130 mg caffeine. A shot of espresso contains 55 to 76 mg caffeine (McCusker et al. 2003). The caffeine content of a single type of coffee purchased from one store of an international coffee company on... 

Air shot (air purge) n. In injection molding, a shot made with the nozzle withdrawn from the mold, so that the expelled melt may fall freely and be caught for measurement of cup temperature or for weighing. 

Zahn viscosity cup n. A one-shot device for obtaining quick measurements in a roughly linear way of the kinematic viscosity of the test liquid, typically a free-flowing fluid.
