If any one could help me I would be most grateful. i was in Brittany in the forest at Paimpiont/ Brocilande and detected 9 bullet casings .
The casings have some markings on the base E on one side opposite side D then followed by 3 on one side and 5 on the other.
This is the only casing that is really clear, the other one as F onside and C on the other, cany see any numbers to distorted.
Its 155mm in length
