Can any body help identify this bullet casing/cartridge

[Paulkent012]

It’s possibly made of brass and had cardboard inside .The end is approximately 20mm in diameter.It has been stamped with the letter k and what looks like the number 2 in Roman numerals.
I live in the uk on the south East coast .Any help would be greatly appreciated.

Kynoch was an ammunition manufacturer in UK. Used a K headstamp.
.50 BMG has a base diameter of 20mm-ish if I recall correctly. It would likely be the most common brass in that size range. I am guessing that your find is a rimless case. Hard to tell exactly from the picture angle. If it is a rimmed cartridge I am clueless as to what it could be.

50-70 or 50-90? Black powder rifle. I had a 50-70 Sharps but no longer have any cases.

This is likely to be something in the realm of late 19th Century black powder big game double rifle firearms such as the Holland & Holland. The cartridge is rimmed and centerfire and looks tubular. If the "end" is the rim width and is about 20mm, the cartridge tube is a bit less than that diameter and may be a "10 bore". These rifles were cited as "bore" much as period shotguns would, such as 10 gauge, 12 gauge, etc. on the USA side of the pond. These were used for hunting large African and Indian game. The "K" on the headstamp likely refers to Kynoch, a well regarded English ammunition firm of that era, even into the 20th Century. As Kynoch headstamps go, this is an unusual Kynoch headstamp, if it is a Kynoch cartridge. It is quite plain.

Probably something like .577 Snider or Martini-Henry.
