Oh, OK. So, opening up brass by fireforming won't work then.

Oh, you say it will? Then what's the difference?? Or are we digging flysh*t out of pepper.

At the time, regular 303 brass was un-necked until, after it was filled. (It makes loading Cordite easier.) Then it was necked, and then the bullet fitted.

As I said, the .410 rounds are made from those un-necked .303 cases. You can achieve a similar effect to the original un-necked .303 case by fire-forming .303 cases in a .401 musket.

I was not to know that you knew how they were really made.
