8x57 with PS Headstamp

Again not my thing but here is a 8x57. Just what type of load is this?. It has a short nickel (?) plated bullet. The bullet is attracted to a magnet.

It could be their full metal jacket load with a flat nose, bullet weight 5.45 g (84 gr) and velocity 535 m/s (1755 ft/s) at 25 m. The bullet catalog number was 53.
The 8x57 is the version with the smaller diameter bullet (8x57J, 8x57I since 1983) bullet of 8.1 mm.
The larger 8.2 mm diameter (8x57JS, 8x57IS) was marked 8x57S on the case.
