Does anyone know what starting shell case/calibre can be used to re-form and make .303 British?

The book by George Nonte Jr. Cartridge Conversions lists the making of 303 British case's from 30/40 Krag brass. You trim to 2.209 inch; size in a 303 British die ; use .311 bullets.
As dreamweaver said buy it. Midsouth list's 303 British at $45.17/100cases and 30/40 Krag at $48.46/100 cases.

.303 British brass is about 10 times easier to get your hands on, than .30-40 Krag. I would definitely suggest buying .303 brass.
Jaguarxk120 is correct, though: If you want to anger the .30-40 Krag shooters, and snap up all of their incredibly hard to obtain brass... It can be formed into .303 British. However, the Krag case is considerably stronger than the .303. You'll encounter a noticeable decrease in case capacity, and a rapid increase in pressures. Standard .303 load data will have to be reduced slightly, to create new starting loads for the reduced-capacity cases.
