Today I pick up what appears to be a brass 32 gauge shotshell in Ferlach headstamped GR ( monogram) / * / 1897 / *
It is a primed empty new sample, 60 mm long.
Here the basic dimensional data:
rim dia: .644" / 16.38 mm
rim thickness: 1.02 mm / .040"
base diam : .570" / 14.48 mm
mouth diam: .525" / 13.31 mm
rim thickness and mouth diam are smaller than my 32 ga sample made by Fiocchi
Is it really a shotshell or is it a German / Austrian standard of the past?
