Some years ago I bought this round that I listed as “unheadstamped 10.4 Italian Ordnance” round in my collection. Its dimensions match those of the italian 10.4 revolver round but I don’t knwo if I am right with my ID. I would like to know the possible country of origin or its maker if possible. Measures are also very close to the 44 Russian round, although the shorter case.
Lead bullet, brass case and flat copper primer. It had a black powder load.
rim diam: .518"
head diam: .467"
mouth diam: .447"
bullet diam ( just outside the case): .424"
case lenght: .843"
