Overview
The 20/577 Alexander Henry was developed and introduced by the Scottish gunmaker Alexander Henry around 1895 exclusively for his hunting rifles.[1][2][3][4][5]
The 20/577 Alexander Henry is a rimmed, bottlenecked centerfire rifle cartridge. The 20/577 Alexander Henry is derived from brass 20 bore cartridges necked down to accept a Шаблон:Cvt calibre bullet like the .577 Black Powder Express.[1][2][4][5]
The 20/577 Alexander Henry fired a Шаблон:Cvt lead, paper patched bullet driven by 6 drams (10.6 g) of blackpowder at Шаблон:Cvt, its ballistic performance replicating that of the .577 Black Powder Express 3-inch. Later versions were loaded with mild loadings of cordite, carefully balanced through trial to replicate the ballistics of the blackpowder version, a copper-tubed lead bullet was also available, offering improved performance against dangerous game.[1][2][3][4][5]
