I've always thought that the 32 44 was bored straight through without a chamber shoulder. Is this true? I have one in my shop that does have a shoulder but I have nothing to compare it to. Were there other cartridges this could have been chambered for? The dimensions are: .352 at the base, .323 at the mouth, chamber length1.080. The bore is .311 and the groove is .320. The closest I can find is the French 1892 Ordnance ctg. Is this possible? All numbers match and it has a short bbl address. The owner has not sent for a factory letter.
