Very neat, was thinking how to make that part on a manual mill! With a lot of bits in the bin lol
Superb!!..
What are you making the brass from?

Bertram make rimmed brass for the .222 Rimmed and the 223 Rimmed.
The Australian’s developed a whole series of rimmed cartridges based on the .303 and .30 Cadet as they had lots of surplus Lee Enfields and Martini action Cadet rifles and imported rifles where very expensive. Things like 243/303 were pretty common from the late 1960’s.
Imagine those Like Browning who made such parts with machines ( often also made ) no modern milling machines but forging, file-work etc
Love it!..@Taffbats
I guess like this on the rotary table, Dogs bone scope clamp from a bit of ally stock on the old mill.

You definitely need the skills and patience on a manual mill, one wrong move and you've got an ornament... lol

From RWS 5.56x50 Magnum cases sized down to 45mm.
It was originally a .222R and I had 120 cases by Super. We chambered it with a short neck a la .223 Rem and so .223 loads were possible as the .222R Super is longer thasn the .222 Rem.
But inevitably they wore out and eventually I had to go to a different parent case.
I had at various times: .221 Rem Fireball rimmed (256 Win magnum cases necked down), a 6.5 Phillips (30-30 International sized down to 50mm, almost straight walled and necked to 6.5), a .357 Maximum, and a .22/357 Max all in Martinis.

.357 Remington Maximum cases can be made from shortened 5.6x50R cases, their base is 10 thou less in diameter all of the neck you cut off. Just did the comparison as I re use split necks after annealing.

BSAs factory address in Birmingham, I was at the apprentice training centre there 1965-66.
I used a 3.5 mm carbide end-mill on a boring operation, I'd like to heat treat it but worried it might alter shape/dimensions. I'll research home heat treat, and probably practice on a spare.
