Cheddite is a class of explosive materials invented in 1897 by E. A. G. Street of the firm of Berges, Corbin et Cie and originally manufactured in the town of Chedde in Haute-Savoie, France, in the early twentieth century.
Lead styphnate (lead 2,4,6-trinitroresorcinate, C 6 HN 3 O 8 Pb ), whose name is derived from styphnic acid, is an explosive used as a component in primer and detonator mixtures for less sensitive secondary explosives. Lead styphnate is only slightly soluble in water and methanol. [3]
The third line listed the model of primer (Zdh, or zundhuetchen), the date of manufacture, and the manufacturer; an "X" between the primer type and date of manufacture indicated it was a type of primer with a low mercury content. C Munitionsfabrik Cassel ("Ammunition Factory at Kassel") – Kassel, Hesse-Nassau, Germany. Closed after the war.
With quick firing guns (those using metallic cartridge cases) the case itself is fitted with the igniting medium; in England these are called primers. For small guns the case contains a percussion primer, usually a copper cap filled with a chlorate mixture and resting against an anvil. [2] The striker of the gun strikes the cap and fires the ...
CCI (Cascade Cartridge Inc.), based in Lewiston, Idaho, manufactures rimfire and centerfire handgun ammunition, including primers for handloaders and a industrial ammunition production line. CCI made the first .22 Long Rifle Mini-Mag rimfire ammunition in 1962 and, in 1975, they developed the .22 Stinger rimfire ammunition, a high velocity .22 ...
Primer reduces the number of paint coats needed for good coverage and even color. A thin layer of paint may still be permeable to water. Water can permeate into the wood and cause warping, mildew, or dry rot. Primer improves the waterproofing of the finish. [4] Primers are not used as part of a wood stain treatment because they obscure the wood ...
Sprengel explosives are a generic class of materials invented by Hermann Sprengel in the 1870s. [1] They consist of stoichiometric mixtures of strong oxidisers and reactive fuels, mixed just prior to use in order to enhance safety.
Comparison of centerfire and rimfire ignition. Centerfire cartridges are more reliable for military purposes because the thicker metal cartridge cases can withstand rougher handling without damage, and is safer to handle because explosive priming compound in a protruding rim is more likely to be triggered by impact if a rimfire cartridge is dropped or pinched.
