The 514 and 430 numbers on the boxes - is that the muzzle speed? What is that in fps?
If so, why did the chart give 675mps? What weight are those bullets?
The word above these numbers reads "Fabrikationsdatum" = date of manufacture, read lot number. The 9.3x53(R) Swiss cartridges were factory loaded with one bullet weight only: 13.1 gramm = 202 grains. MV from a 68cm = 26" barrel was given in another table as 695 m/s = 2280 fps, same for both the rimmed and rimless version.
