Why do you believe it's a loop?
Please show tcpdumps. Loop will be visible on loopback
(tcpdump -nlilo).

Put your squid on port 12345, REDIRECT to 12345 intead of 8080.
However I doubt it's a loop, I think REDIRECT never apply to
locally generated packets.

I keep this comment on top of my firewalling scripts:

### filter This is the default table (if no -t option is passed).  It
contains
###        the  built-in chains INPUT (for packets coming into the box
itself),
###        FORWARD (for packets being routed through the box), and OUTPUT
(for
###        locally-generated packets).
###
### nat    This  table is consulted when a packet that creates a new
connection
###        is encountered.  It consists of  three  built-ins:  PREROUTING
(for
###        altering  packets  as  soon  as  they come in), OUTPUT (for
altering
###        locally-generated packets  before  routing),  and  POSTROUTING
(for
###        altering packets as they are about to go out).
###
### mangle It had two built-in chains: PREROUTING (for altering incoming
###        packets  before  routing) and OUTPUT (for altering
locally-generated
###        packets before routing).  Recently three other  built-in
###        chains  are added: INPUT (for packets coming into the box
###        itself), FORWARD (for altering  packets  being  routed  through
the
###        box),  and POSTROUTING (for altering packets as they are about
to go
###        out).
