You have sure gone to a lot of trouble. I just take the .303 case, insert it in a wood block, and take a thousand of so off the case head with the disc sander, so my bolt will close on it. Then I anneal the whole case, by turning it cherry red with a propane torch, and let it gradually cool. I then prime the case, load the it with about 6 grains of Unique, top the rest of the case up with Cream of Wheat, close it with a wax plug than fire it in my .410. If the low end of the case hasn't fully formed out, it will when you fire the first full charge in it. I usually use Berdan casings drilling out the primer pocket so it can take a shotshe!! primer. You have to go carefully so you don't over expand the primer hole, I usually use a hand reaming tool for the last little bit. The body of a .308 sizing die can be used to fold the case around in order to crimp it, watch you don't over crimp, you can get vertical fold which will damage the mouth of the brass, so it will tend to split.
