Default Why do primers back out when firing just a case with primer?

I broke apart a few 44 mags. Removed bullet and powder.

Put the primed case in my 629 and ignited the primer. The primer backs out enough to jam up the cylinder.

I mentioned this in another post and Bruce said it's normal. My question is why? Is it because there is no back pressure or what?

Also, for the poster(silvercn) that was concerned with lead. I fired three of these and my barrel and forcing cone were filthy. I ended up cleaning my gun as much as if I took it to the range. I could not believe how much "crud" a few primers could create!
