Thank you Mr. Tark for mentioning the .244 H&H, it's an interesting cartridge. I've never seen a rifle is this caliber and can't remember how I came to have the sample shown in pic. I expect very few rifles and ammo were made. Another British 6mm cartridge is the H&H .240. I've hunted deer in Scotland with a .240, with a pretty Holland &Holland rifle they had loaned me in hopes I would buy it. Which I didn't. The 240 ammo I hunted with had a Norma stamp on primer so I assumed they made the whole catridge.. It is quite similar to the .240 Weatherby Mag and I suspect it gave Roy Weatherby the inspiration for his 6mm Mag, even borrowing the name. Guessing, but Norma may have also made the .244 H&H, as the sample I have has a steel jacketed bullet like Norma once made. Attached is a comparison pic of the two British 6mm, note Norma stamp on primer of .240.
