Anyone have any information on a cartridge called the .222 Super. There's a custom Martini Cadet rifle I'm looking at in that caliber and I'd like to know more about the cartridge, such as ballistics and brass availability. The seller is describing it as a rimmed .222, but my recollection of that cartridge is that it was called the .222R. Is this a blown out version of the .222R or something altogether different?

FWIW, the seller reports using .222 or .223 dies to neck size and a .38 Special caseholder.

Thanks for your help.

Rem

.222 Super is better known as .222 Rimmed. It was brought out by the (now defunct) Super Cartridge Company and was pretty popular here in Oz as a chambering for Martini Cadet actions. I have one of these myself.

The brass is still made here, by Bertram. If you were stuck I guess you could also make it by resizing and trimming 5.6x50R. You could also use .222 Remington brass or ammo, but unless you get the extractor changed to suit the rimless round (which can be done) you'd need to use a small screwdriver or similar to extract the cases.

The dies to use are .222 Remington, with a .38/.357 shellholder. There's nothing too difficult about reloading this round. The action is very strong but extraction is not, so that tends to be the limiting factor: start with .222 Rem starting loads and work up until extraction gets sticky, then back off to find a load which is accurate and extracts easily.

The 222 Super is the 222 Rem with a rim. Nothing more than that. The "Super" in the name is the name of the company in Australia that manufactured the brass and ammunition. Brass can still be found here and there in the USA.

The case has been wildcatted here in the US, in Canada, and in Australia too, I'm sure.

It looks as though Dan was posting as I was typing.

Thanks very much. That's exactly what I needed to know.

40X,
Check out my post re/Herter's .222 bullets. I have about 120 of them (40gr semi-pointed).
No one believes them to be "collectible", so if you're interested, let me know and we'll work something out. Not believed to work well in my Hornet, so I have no need for them.

You could neck down 357 maximum cases to create usable cases which are slightly short.
