Isn`t #5 a Isreali HS ?

[EagleEyes]

I may have misled you as the headstamp on Round 5 is I think Eastern European (Russian) or Middle Eastern (Hebrew) as it uses a different alphabet which I think may be
У Л translates to Y L or ЦП to T T. I didn’t think Lapua in Finland would use such an alphabet, please see image for Round 5.

[TonyE]

It serves me right for looking at the listing and the title and not the images!

No.5 is definitely Israeli. I identified it from the "KP" which is Lapua. It is Hebrew by the way, not Russian. I also did not look at the picture of No.7, the .50 Spotter (BAT). Mea culpa!

The .50 Spotter should not have a ball bullet. It should have a two coloured tip.usually yellow and red, but there were dozens of different colour combinations on the development rounds. It has probably just had a M33 ball bullet put in the case.

Attached are a few examples of Kynoch .50 BAT rounds.

Sorry about the confusion,
TonyE
