There is another conversion for the 303 that is easier to make, dies are much cheaper and reamer is easily made.
It is called 306 Confederate Sabre and basically made from a 30.06 chamber reamer with the base dimension size and location ground for the 303 Brit. Thusly you have a Confederation of 303 Brit case with 30.06 neck and shoulder.
Dies are simply made by chucking up 30.06 dies in lathe and trimming off bottom of die thus a used set of 30.06 dies are used to load it.
The new case is fireformed and once done holds about six more grains of propellant than the normal 303.
I used the base dimension for Greek 303 brass which I think was .454" so the brass isn't stretched way out as it is in normal 303 chambers.
Dave Manson (Manson Precision Reamers) has the drawing and made the reamer for me.
The curator of the Royal Armouries Museum in England found out about the Sabres and asked me for dummy rounds to add to their collection. I also made one in 6.5 and 7MM Confederate Sabre which are both loaded with 7MM Mauser dies and 6.5X55 dies.
Hit me with a PM for more info.
