400 Jeffrey
This is the 450/400 3". My notes have two different dates for the introduction of this cartridge, 1896 and 1902. The 1896 seemed early for a NE, and I had dismissed that date. I saw mention of the 1896 date again recently, so I'll see what people here know about it.

cal30 1906I wonder if the earlier version was strictly a blackpowder loading.
Stick with 1902 as the start date for the 450/400"S" Jeffrey. It was only loaded as a smokeless round .
The 450/400 31/4" cartridge first appeared as a blackpowder round in the 1880's , but that is a differant round to the Jeffrey.
