last time it became a little bit more colourful here but this is always the 9,3x53R Finnish thread and we have a mission in the name of science.
my special thanks to Bokmal who found another ammunition variant and recognised the relvance for our search.

what we have here is a 15 gramm FMJ spitzer bullet load in the 9,3x53R with v/0 of 735 m/sec

naturaly my first thoughts were going to the currently available Norma load 9,3x57 Jaktmatch.

again a 15 gramm FMJ spitzer with a v/0 of 675m/sec
like the name suggest a cartridge loaded for target practise. that may have been also the reason for this load. bokmal point me also to the fact that it would be a good bullet for hunting the black woodgrouse and fur bearing animals like fox too.
