Yes, you can.

All day long. Any shotgun can handle shorter shells than it is chambered for as long as they are the same gauge.
Is it chambered for magnum shells? If not, the answer is NO.
The length of the chamber in a 2 3/4 inch chambered shotgun is 2 3/4". The longer 3" shotgun shells will not fit in the chamber, being 1/4" too long. You can shoot 2 3/4" shotgun shells, of the correct gauge, in a 3" chambered shotgun.
12-70 is frequently used to indicate the gauge of the shotgun followed by the length of the chamber in millimeters. In the US, or non-metric measurements, that means a 12 gauge shotgun chambered for 2.75 inch (usually read two and three quarter inch) shells. Sometimes, you'll see 12-76 to designate a 12 gauge shotgun chambered for 3 inch shells.
The Mossberg 9200 can accept 2-3/4 or 3 inch .12 gauge low brass shotgun shells.
This is a Browning Auto-5 Shotgun, 16 guage made in 1950. It is chambered for 2 3/4" 16 ga shells
yes 2 3/4 shell will work in a shotgun chambered for 3in as long as they are of the same gauge
The Mossberg 500 shotgun typically takes 12-gauge shells, but it is also available in other gauges, such as 20-gauge and .410 bore. The shotgun can accommodate both standard-length shells (2.75 inches) and longer shells (3 inches) in the 12-gauge version. Always refer to the manufacturer's specifications for your specific model to ensure compatibility.
Yes but not the other way around .You can not use 3" shells in a 2 3/4 chambered gun.
