Isn't that just another way of saying 'starting to extract the case before completion of the firing process'? process defined as " a series of actions or steps taken in order to achieve a particular end"....also as you say 'BEFORE it is fully chambered',are you saying it does fully chamber?...if this is the case then surely the rather hot brass case would take on the form of the chamber and be extracted/ejected without a 'blown out' shoulder and neck?

I wasn't arguing boss,I was asking questions,you know more about these things than I ever will!.....mind you I have never seen angels on a pin head but I did see an elf on a toadstall once! :tinysmile_shy_t:
Mark I didn't say it extracted before the firing process completes,that would be a rather stupid thing to happen,I said it started to extract and even after reading Tony Williams piece it seems to amount to the same thing to me?
One point of interest I have come across concerning the original thread....I had a 'grub around' in my 'odds and sods' box and pulled out fired Oerlikon cases,three of them were ST manufactured and all had the identical base distortion as the one in the first post yet RG,RH and R.C.C did not....so could this base distortion be unique to ST?

....although load details can be found on the side of the case,just above the extraction groove in the same manner as on 20x110 Hispano,on later British 20x110 Oerlikons.....also the fired example shown does not have the same shoulder and neck profile as an unfired example due to the Oerlikon gun starting to extract the case before completion of the firing process therefore 'blowing' the neck and shoulder out,which may explain the 108mm case measurement
Cheers
