Hey JD,
Just in case for future use, you might look into getting and modifying or building a case extractor similar to this one,
Broken Case Extractor from Midway
I have loaded and shot quite a few 303 British rounds in the past and have used a very similar tool for pulling out broken shells in both the rifle and the die. Similar as to what your looking at. Generally in the die I just push it in by hand until it goes over the end of the neck and a quick tug and it is a done deal. One could probably be built or modified easily to your case deminsion.
Just an idea.
While looking I think I found a page from Roy's garage workshop here,
Hometools
Sure sounded familiar anyway. [img]/ubbthreads/images/graemlins/grin.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img]
