Is it an "elephant gun"?
The "Express" would indicate this is a double rifle. Purdey used the model name Express for their breech-loading double rifles for dangerous game, such as elephants, cape buffalo and rhinocerouses. There were several cartridges developed for the safari hunter such as the .450 Black Powder Express, the .450Nitro Express (aka 450NE, Nitro was the British term for smokeless powder). Later the 470NE, 577NE and 600NE were developed. Al_in_Ottawa
Beauty, but the recoil would knock me on my ass...once.
It reminds me of a story I read about Sir Henry Baker, thedesigner of the Brown Bess musket the Brits used in theRevolutionay War. He developed a 12 bore musket. It wasa 73 Cal. flintlock with an almost 600 grain ball. He saidhe only fired it once!Here is a .600 Nitro Express round:http://cdn0.wideopenspaces.com/wp-content/uploads/2015/01/the_600_nitro_express_is_typical_of_huge_bore_elephant_gun_rounds.jpg
Gott in Himmel! Nope, not even once. I like my shoulder right where it is, thank you.
