Tell me about this round.

[jmr40]

I found a dud round someone left at the range yesterday. KYNOCH and 577/450 are stamped on the rim. Looks like a 30-30 round with a long neck on steroids. It is a rimmed case about 2 1/4" long. Approximately 50 cal bullet, solid lead with what looks like orange paper between the lead bullet and the cartridge mouth. The cartridge is about 3/4" in diameter at the rim. Stays that way for 1 1/4" then tapers down with a 1" long neck.

This is a new one for me. Any history would be appreciated.

Old British caliber, .577/450 Martini-Henry

Kynoch is an old brand, I don't think they still manufacture

That was the British service round for the Martini-Henry single shot from 1871 til 1888.

The shooter was pretty extravagant to leave one behind, even if a misfire.
J&G has old stock Kynoch ammunition for $49.95 a box... of ten.

British cartridge nomenclature is a little different. They put the parent case first, then the caliber it was necked to. In this case, it's a .577 Snider necked to .450.

Kynoch is back in business. Expensive stuff.

FWIT - The author Ernest Hemingway had a double-barrel .577 he called his "big gun."

Kynoch website for this round says "AVAILABLE FROM KYNOCH AS CASES ONLY"

I wonder if they mean you have to buy the ammunition by the case (vs by the box), or they only sell the brass, not the loaded ammunition.

Means they only sell empty cases for handloading.

In case there's any confusion, Midway has new Kynoch ammunition. Don't see any for the .577/.450 but they do have .450/.400.

I picked up a .577-450 round at a gun show some years back, to add to a cartridge collection I have, definitely the only one like that! Paid $1.50 for it.

Darned if that isn't the longest neck I have ever seen on a case! What a weird design.

Century (and others) are selling new old stock Kynoch. http://centuryarms.biz/proddetail.asp?prod=AM1706&cat=63 Most folks that shoot their MH's make their own from 24 guage brass shotgun shells. That is how these were made.
