the particular set of calibres remington happened to mix up in this case is not significant.
"30-06 stamped .270" could have just as easily been ".223 stamped .300 Blackout" or "12g stamped 20g" or "270 stamped 308" or any other of the endless number of combinations that could be lethal.
The point is who's to say that if an error does happen again, which this proves to be possible, you can't be sure it isn't a more dangerous combination. Just because it was "OK" this time doesn't mean it will be if there's a next time. That's what's meaningful about this.
Speculating about what could happen some other time contributes little to what happened this time.
The OP declined an offer from the business where he bought the rifle, before going to the 'net.
The distributor also offered to help, but they need to see the rifle.
The OP did start two threads on this site, and another elsewhere. He did substantial editing to two of the three initial posts.
There is no speculation. We are discussing exactly what happened. The barrel was stamped one calibre, and chambered for another. IN GENERAL - This is extremely dangerous and possibly life threatening.
Unless you're suggesting that Remington knowingly chambered this dudes rifle in 30-06 and stamped it 270 because it wouldn't be so bad if he happened to fire 270 through it, the "speculation" bit is not valid.
This thread is about one situation, where a specific caliber stamp did not match the actual barrel. Because of the .30-06 barrel, the .270 data stamp poses no danger; .270 ammunition fired in this particular rifle will not cause damage to either the rifle or the shooter. When Remington proof tested the rifle, no doubt a .270 proof load was used. Other combinations could indeed be dangerous, but this one wasn't. This situation is not acceptable, which is why both the dealer and the distributor have offered to resolve the situation.
What compensation do you want?
New gun?
Gas money to and from hunt camp?
Pain and suffering?
$10,000 for bring in danger?
1000 rounds of ammo too?

It's clear that Remington does not reliably proof their guns. You can find several examples of rifles with the REP "Proof" marks with half-cut chambers, or no chambers at all.
This would be an example of a reportable "near miss" by Remington. It only takes so many "near misses" until you're statistically likely to hit an "incident".
