Yes, some chambers are ridiculously long - I had dealings with a Parker Hale that had been rebarreled with a Hawkins tube - we called it the .308&1/2...

The initial flow forward of brass is unavoidable, and even if you fire it in a minimum spec chamber and the cases are long to start with i.e. a tight fight the brass will start moving forwards and expanding at the web. If the cases are annealed and the neck work hardening is looked after the case head issues can't be solved anyway - the end result is the cases will eventually be consumed.
