To me, the most interesting aspects of Mark Daiute's case neck separation is: 1. Why did it happen? & 2. Where in the case neck/shoulder area, did it happen?

It will be interesting to hear how things turn out. It would also be interesting to see photos of the case and neck section (and chamber cast, if he goes that route).

I am not trying to encourage 'Bubba' behavior in suggesting a Tap as an improvised 'stuck-case remover'. Years ago it worked for me in carefully removing .303 British and .310 Cadet cases that had head separations. At the time, I had little recourse to other solutions.

Attached, is a photo showing how a 5/16" Tap can get a 'bite' in an expanded .30 cal. case neck. A .308 case can be crimped on the shank to serve as a 'drive-shaft'. A sheet metal screw in the flash hole would facilitate turning the Tap a minor amount with a screwdriver or nut driver.

As Parashooter and FredC state, this is a risky route to go.
