....."Since the barrel shoulder has been machined back the barrel is now scrap, and will never be usable in .303 again."
The shoulder can be carefully machined, and a breeching washer fitted. Makes it very easy to reuse the take-off .303 barrel.
.303 barrels are 1-14 pitch, so it is easy to calculate how much the shoulder must be dressed, and how thick the breeching washer needs to be, in order for the timing to be correct.
