Anyone have a pic of what the Chamber should look like? Also with a snap cap in chamber and magazine out I can see the back end of the round. Is this normal?

"Exploded view"

Chamber Dimensions (SAMI)

You can see the rim clearly when the cartridge is chambered

The entire back groove for the rim is completely unsupported by the barrel. That's normal.

Go to a drawing of a 308 cartridge, such as on wikipedia. The 0.1516 of the tail end is unsupported. That area is where the extractor snaps over. The back end of a cartridge like that is very thick walled. No issues.
