Black powder cartridge rifle (BPCR) refers to modern shooting sports which employ black powder cartridge rifles. These firearms, often of the type referred to as " buffalo rifles ", are single-shot firearms using a fixed metallic cartridge containing black powder , which launch heavy projectiles at relatively low velocities.
The .577/500 No. 2 BPE was developed as a black powder round some time before 1879 by necking down the .577 Black Powder Express to .507-inches (12.9 mm) [2] for use in single or double rifles, as well as a variety of Martini-based lever rifles. Like the .450 Black Powder Express, the .577/500 BPE came in several case lengths, the most common ...
The .577 BPE originated around 1870 with the 2 1 ⁄ 2-inch variant. [1]The 3-inch cartridge has survived to the current day as the .577 Nitro for Black, the same cartridge loaded with mild loadings of modern smokeless powder, carefully balanced through trial to replicate the ballistics of the Black powder version.
The first drag racing slick was developed by M&H Tires (Marvin & Harry Tires) in the early 1950s. It was the only company in the world that produced and sold original drag racing tyres. Drag racing slicks vary in size, from slicks used on motorcycles to very wide ones used on "top fuel" dragsters.
The .450 Black Powder Express is a rimmed, straight walled, centerfire rifle cartridge designed for use with blackpowder. It was available in a number of loadings with bullets weighing from 270 to 365 grains (17.5 to 23.7 g), all driven by 120 grains (7.8 g) of black powder. [1] [3]
A US patent to Goodyear [4] also claimed sipes improve tire traction, and tend to close completely in the tire "footprint" on the road. A 1978 study by the US National Safety Council found siping improved stopping distances by 22 percent, breakaway traction by 65 percent, and rolling traction by 28 percent on glare ice .
The 3-inch and 3 1 ⁄ 4-inch .500 BPE cartridges have survived to the current day as the .500 3-inch Nitro for Black and the .500 3 1 ⁄ 4-inch Nitro for Black, the same cartridges loaded with mild loadings of modern smokeless powder, carefully balanced through trial to replicate the ballistics of the Black powder version. [2]
The .500/450 No. 1 Nitro for Black was the same cartridge loaded with mild loadings of cordite, carefully balanced to replicate the ballistics of the black powder version. Unlike other similar black powder cartridges, such as the .450 Black Powder Express and .500/450 Magnum Black Powder Express, the .500/450 No. 1 Express never became a Nitro ...
