Due to many, many reasons I'm not going into, I'm putting a .308 barrel on one of my 303 British rifles. I have measured piles of empty brass from 1/2 dozen 303 British rifles and eight 308 rifles and have found the fired brass necks of the 308's and 303's were all about the same. In many cases, the fired 308 brass had larger case mouths than the 303 British. It just doesn't seem that that .003 makes much of a difference....however, it might.
My question is this. Do I need a custom reamer for this 30/303 British just to be safe? I'm not against it. This is going to have a Krieger barrel and the action and rifle are certainly unique but I'm not sure that any difference will be noticed in any way.
