   iptables -nvL

The -v is the important bit here, you get 'packets' and 'bytes' counters
per rule then.  Adding -x will give exact byte numbers, rather than
summarising to K/M/G as the number grows.
  You can use -Z on a table to zero the counters when needed.

  The only mention I can find of such in the man page is:

BUGS
       Check is not implemented (yet).

So I guess not.
