9.3mm Cartridges
By Brian Clark
I was working on an ongoing project of mine and was researching information on the
9.3mm caliber series of cartridges. I had purchased an M88 rifle built by Carl Stiegele of
Munich in 1892. It had been rechambered and rebored to a cartridge I was unfamiliar with.
It turned out to be chambered in 9.3 x 53 Swiss. I have had a lot of fun with this
cartridge, forming brass and finding bullets.
This project lead me into the world of the 9.3mm cartridges. I had believed that this
would be a small, simple group of cartridges to research. Was I wrong. I turns out that
there are over 40 cartridges in this caliber with some eighteen based on the British 360
Express case alone. I hope to present a brief examination of this group of cartridges.
I intend to present a couple of cartridges each month as time and space permits. I hope
you find this as interesting as I have.

| Historical Data: |
It is not known exactly when or whom developed the .360 No. 5 Rook or
Revolver cartridge. Because of the cartridge's dual naming the situtation is confused. It
was used in British revolvers and was even used at a match at Wimbledon in 1878.
The .360 No. 5 cartridge is found in a number of different loadings from lead round nosed
bullets, hollow point, shot, and blanks. Bill Fleming lists 17 different variations in
bullet and powder. Black powder, Cordite, Axite and Revolver Neonite by Nobel was used to
load the cartridges. Both Eley and Kynoch manufactured the cartridge. |
