History of the .577 Black Power Express cartridge:
The 577 B.P. Express (B.P.= Black Powder) was introduced in the early 1870's with a 2&1/2" case and later in 2&3/4", 3" and 3&1/4" versions which basically replaced the 577 Snider variants.
The Black power charge was a huge 135 to 190grains of black powder.
The 577 B.P. Express was changed to the .577" Nitro Express in the early 1900's when
it was loaded with (the then) new "Cordite" smokeless powder.
This is a very hard item to find today.
