Here's a pic showing 30/40 made from PRVI brand .303 brass. From left to right, unfired 30/40, .303 sized in full length die, .303 sized simply by closing the bolt on it, and .303 unsized. Sizing it by closing the bolt is easy as the neck/shoulder is annealed on the PRVI brass. Of course the neck is still a bit large for .308 bullets, but I use .310 bullets, so it isn't a problem for me. At $20/100 less than what Grafs last charged for 30/40, it'll work for me!
