I found these in Eastern European forrest, ~50 km. from 1944 German defensive line. Whole place was littered with shrapnel of warious calibur artillery shells (and probably even aviation bombs). There is something like U-form trench (lenght ~10 m), with fragments of completely rotten tarpaulin in it, bullets were stuck in a parapet, 20 cm. deep, all within 1m. square. No cases around.
There are 8 of them, in quite good condition, you can even see red paint.
Maybe it is possible to distinguish, whether they are WWII-wintage, or modern, left there by some guy with a Glock? I have no evidence, that trench and shrapnell really are from WWII, as some locals say it all may be post-war, remains of improvised soviet artillery training ground. Good condition of bullets support this theory, but again, they were found in a sand - it preserves metals well.
Are there any differences between WWII-era german Parabellums and modern ones? Can these bullets be called war relics? I’d really appreciate any help!
