Hmmmmm so I start trying other cases that havent been sized and I cant get any fired cases from my gun to chamber, none.
yes they are from my gun fired before.
If in your neck sizing process you bulged the shoulder of the cartridge by pushing back on it to hard you may have caused a chambering problem.
To check
Pawildman theory... do you still have a shell that you have not neck sized? If you do try chambering it, if it chambers you probably have you neck sizing dies set wrong....
Just guessing....
