This round is one of a bunch that Aaron and I got almost 2 years ago. The photos supplied by the source were taken at an angle and it proved difficult to determine the caliber. I thought there was a possibility that they might be .450 Short C.F. so I got excited, but when they arrived and we were able to measure them properly they were clearly not .450’s. What they were is an open question which is why I’m seeking opinions.
The headstamp is “РУССКИЙ П З [star] short for Русский патронный завод (“Russian Cartridge Plant”) which was the name used by the Inarov factory on the outskirts of Moscow up until 1899 when it became part of Cartoucheries Russo-Belge.
I did run the rounds through a .450 gauge and they rattled around like a pea in an oil drum !
The dimensions are as follows:
Rim Ø: 0.498 (12.65 mm)
Head Ø: 0.453 (11.51 mm)
Mouth Ø: 0.446 (11.33 mm)
Bt Ø: 0.433 (11.00 mm)
Case length: 0.655 (16.64mm)
Brass case & primer, lead bullet. O/A Weight: 246 grains (small hole in side and powder removed).
I ran the dimensions through the ECDV and got likely hits on .430 C.F., .440 C.F. and .442 (the latter being a GFL product with an abnormally small bullet diameter). There could be other possibilities ……
I have no idea what the old Inarov plant was making in terms of revolver ammunition, or even what was popular in Russia at that time. Has anyone seen any advertising from that period (i.e. pre-1899)?
So ladies & gentlemen – your thoughts??
