I was really wondering how you would clean those tiny grooves and what would happen if they were not cleaned properly and carbon was allowed to build up. Could it have the reverse effect and make a shell harder to extract?
No more of a problem than a dirty chamber. A sharp dental pick would easily remove carbon or debris.
With any military rifle one of the critical elements is how well they can perform when muddy, sandy, wet, dusty etc which is why you find ways to create channels and grooves for crap to move to in order to keep it from gumming up or clogging the operating system.
This is actually where the idea for fluted bolts came from. Of course a fluted bolt is also less likely to freeze and stick to the point you can't operate the action in sub freezing wet weather..
