Can't find 6mm brass

I can't find any 6mm brass for sale. Does anyone know how to make it from other brass?

243Win? There are many 6mm cartridges out there!

Trying to make 6mm Remington brass for a 6mmAI

Midway has 7x57mm Mauser and 257 Roberts in stock at the moment that you could neck down as an option if nothing else works out.

7x57mm Mauser is that the parent cartridge?

Yes, and the 257Roberts is derived from it also.

I have a hundred rounds of 6mmAI that i might sell. They have been annealed and full length sized. Probably fired twice.

http://www.lohmanarms.com says they have it but i didn't go so far as buy it to see if it says backordered. might want to call them and ask

Pick up some Norma 7x57 or 257 Roberts +P and neck down. Will probably have to trim necks.

Be careful when necking down to measure the neck diameter of a loaded round. Going from a 7x57 RWS brass to 244 I had to turn about 0.006" off to get 0.002" clearance in my 0.272" neck chamber. I strongly recommend you get some CerroSafe and make a chamber cast so you now exactly the size neck you have. Granted most factory chambers are on the lose side. You can really build wild pressures if the chamber is to tight. Luck in your search. I gave 100 6mm RP brass to young man that recently inherited his fathers 6mm Rem and a friend was teaching him to reload for it. Tim
