There is no "break in" shotgun. A "break open" shotgun is a single barrel, double barrel, or combination rifle/shotgun which breaks open in the sense that a lever will unlock the action, allowing the barrel to pivot at a hinge at the front of the receiver, pivoting the rear of the barrel up to expose the chamber. A shells may be loaded into the chamber and the barrel pivoted back to close the action.
The act to "break in" a shotgun means to fire it a few times to loosen it up.
Burn it!

depending on the make, age,and condition that shotgun could be worth nothing up to $3000.
No you won't break a 12 gauge shotgun if you only do it once or twice. If you flick a shotgun's action open or closed to often. You can {1} loose other nut's & screw's that are holding different part's on to the shotgun. But {2} in most cases you will end up with a very loose front hinge pin. And that loose hinge pin causes both of the barrel's to become misaligned with the shotgun's frame. Making it harder for you or anybody else to close the shotgun.
it depends on if its a break over or if its a semi those are some of the more simpler kinds
