12-70 is frequently used to indicate the gauge of the shotgun followed by the length of the chamber in millimeters.

Sometimes, you'll see 12-76 to designate a 12 gauge shotgun chambered for 3 inch shells.
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.
