I have a 308 with a match chamber. When measuring the case body at the thickest part towards the bottom i get:

New unfired 308 case .464
Fired case .470

is it normal for a match chamber to allow a case to grow this much? I have been just neck sizing and it has been working fine, i went and tried to FL size the brass and got the first case stuck, it was very hard going in even with lots of lube. Has the case grown too much to be resized? Can i use rounds that i neck size only in other guns or will the case get stuck? I am a bit puzzled, thanks guys.
