Today I got two .320 short rounds.
One is unheadstamped, folded head construction, with rounded copper Berdan primer cup. The bullet is solid RN lead. When pulled it contained black powder. Even though it is unheadstamped it resembles early Eley rounds.
The other is headstamped "- ELEY - .320, solid head construction, with flat copper Berdan primer cup and no headstamp. The bullet is solid RN lead . When pulled it contained fine revolver cordite.
What were the dates these loads were produced between?
