Thank you Roger tor the information on the Tabatiere round and the other info you have sent me.
I only got a few minutes with the collection this weekend so have nothing new to add for now. In order to improve my knowledge I intend concentrating on .303 for a while so this might well be something of a .303 thread for a bit

I am back again next week so will try to have a picture then of the headstamps of the .303 posted earlier.
I thought other members would be interested in seeing the Bisley round and hope you don't mind if I relay verbatim the info you sent me:
"When the NRA moved to Bisley from Wimbledon in 1890, the Volunteers were still using the .577/.450 Martini-Henry, although the Regulars had started to use the .303 in 1889. The .303 wasn't used at Bisley by the Volunteers in any quantity until about 1898. In that year the NRA asked the War Office for 450,000 rounds for issue during the main "Imperial" Meeting in July (in previous years they had only asked for 50,000 rounds), and they specifically requested that the cases be specially marked (to avoid people using their own ammo instead of the "issue" ammo), and also that the packets be specially marked.
The War Office each year up until about 1910 blackened the cases of this special Bisley ammo, sometimes the whole case, some times just the top or bottom half, or the middle third, the markings being different for each year. Some of the markings we know of, many we don't, unfortunately (a lot of the records pre 1907 got thrown away in the 1960s to make more room!!) so this packet of yours is very interesting from a historical perspective.
The usual "military" style of packet is as the "red print on buff paper" that you have on the other packet of .303 (Mk.IV Ball if I see it correctly), and there were usually 10 rounds in the packet. Because a lot of the NRA's competitions were "1 sighter and 7 to count", they usually asked the W.O. to supply the ammo in packets of 8, and it is possible that your packet is of this type."
