I just purchased the CDNN TAR213 20" barrel for a REM 870 Mag/Express. The sales guy assured me I could shoot both 2 3/4" and 3" shells from the barrel.
On the barrel it notes " USE 3 IN SHOTSHELLS ONLY IN only in magnum receivers."
Why would this be? What would be different about this barrel from the original 870 that would prohibit shooting the shorter round?
I'm not concerned about patterning here; it is a cylinder bore. It is a "stuff in the fan" point and click device intended for up close defense work.

You can shoot shorter shells in that longer chamber. The problem you MAY
have is feeding the shorter shells through the action, but I'd bet likely
that won't be an issue.

But since the OP said it's specifically intended to be a SHTF weapon -
which presumably means that pulling it out indicates an "It's *GOTTA*
work *EVERY* time" life or death situation - would YOU bet YOUR life on
it?
</Devil's advocate>
I do tend to agree that the chances of trouble are slim. Which, to me is
acceptable if I'm shooting at nothing more dangerous than vicious
squirrels or ducks. But if I'm going to be dragging out a weapon whose
express purpose is to keep me alive in the face of an oncoming "goblin",
I want one that's going to go "BANG" every single time I cycle the
action and pull the trigger.
(That's part of the reason my sidearm of choice is a wheelgun rather
than a slider - unless my ammo has gone bad, I *KNOW* that six pulls of
the trigger are going to result in six anti-goblin pills heading
downrange)

The "sales guy" was correct about the barrel. However, Remington makes
an 870 Express and an 870 Express-Super Magnum. Who knows what a
"Mag/Express is? The warning on the barrel is telling you that the
barrel is chambered for 3 inch shells but MUST be used with a receiver
that is rated as a "magnum receiver" if you are going to fire 3 inch
shells. Not all receivers are rated for 3 inch shells although they may
accept barrels that are suitable for 3 inch shells.

Thanks for your replies.
I was in the process of tidying up the original message when some
combination of keystrokes made it SEND before I was ready. I hate it
when that happens.
----> The shotgun is an 870 Express. It can shoot 2 3/4" or 3"
shells. <----
Without making a chamber cast, the two barrels look to be similar, if
not identical, from the chamber end. The warning I referred to
earlier just does not make sense to me -- 'USE 3" SHOTSHELLS ONLY IN
MAGNUM RECEIVERS.'
The barrel was made in China for CDNN; the finish seems better than
what I have read about for the Mossberg 20" barrels for the 870.
While we have no idea what quality of steel was used, from all
appearances the people who made the barrel seemed to care about what
they were doing. It looks great, the mag ring silver solder looks
good, and the gold bead is precisely done.

I've also read that Remington was a bit schizoid regarding labeling of
these shotguns. Some have the word "magnum" in some on the receiver,
and some do not but will still shoot either 2 3/4" or 3" shells.
This is not to imply that they are all magnums. Mine is, if you
consider 3" a magnum, or, am I missing something here?

It's fairly simple. The Remington 870 receivers designed to accept 2
3/4-inch and 3-inch shells are marked 870 Magnum. The 870 receivers
designed to accept 3 1/2-inch shells are marked Super Magnum. (should
I make "receiver" all caps?)
The markings on your gun mean that if you want to shoot 3-inch shells
you must have (1) a receiver designed for using 3-inch shells as well
as (2) a 3-inch chamber barrel.
The markings on a Super Magnum receiver mean that you can shoot 3 1/2-
inch shells as long as you also have a 3 1/2-inch chamber barrel.
What's stamped on your barrel may just be read as unclear grammar.

Your new barrel will cycle 2 3/4 shells with 100% reliability.
The reason you can only use 3" shells in guns built for them is the
increased pressures involved in the 3" loads.
Most new barrels from remington and knockoffs from others chambered for
3", will accept 2 3/4" shells and come with the same caveat.

The warning is there so you don't stick the barrel onto an older 870
that was made for only 2 3/4 shells.

Exactly. All 870 barrels will fit all 870 actions, but you shouldn't mount
that barrel on a 2-3/4" receiver.
I have an Ithaca 37 that I rebarreled a few years back. The receiver is 2-
3/4" but the barrel has a 3" chamber. 3" shells will not cycle through the
action, but 2-3/4" shells work just fine.

Ah! Grammar! Why didn't I see that? Engrish!
Since the sentence was well constructed I didn't consider other
interpretations of the warning. Maybe the barrel warning should have
read,
"'USE 3" SHOTSHELLS ONLY IF YOU HAVE A MAGNUM RECEIVER"
That sure explains it. The original message could be interpreted this
way, or written this way if EVEN IF one's first language was English.
People who write warnings usually know what THEY (the writer) mean,
but not necessarily what they have written.
~~~
This is where I got the idea that the shotgun is a 3" chamber (I
bought it used from a widow lady); I've not had it to the range yet,
have no 3" dummies, and don't wish to load it in my suburban garage
with a live round to test chambering:
#From Wikipedia entry on Rem. 870:

Express =96 Matte blue/black bead-blasted with laminated hardwood or
synthetic stocks and chambered for 2 3/4" and 3" 12 or 20 gauge
shotshells. All Expresses have been chambered in 3" in 12 and 20
gauge, but markings have varied.
#END QUOTE<
Note above, "...but markings have varied" and that Express models are
allegedly all 3" chambers in 12 / 20 ga.
Thanks for the inputs.

Geez. Like I said, the author always knows what he means...
When I refer above to "the two barrels", I refer to the original REM
barrel in a conventional length with choke tube vs. the replacement
CDNN 20" barrel.
Man. It's easier to talk than to write.
thanks again to 'yall.

Glad that's cleared up. New topic; is it called a clip or a magazine?
