Break open.
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.
Since you didn't indicate if the round in the chamber had fired, your best idea is to take it to a gunsmith.
When the action is open, nothing is holding a shell in the chamber, and the firing pin is several inches away from the shotshell primer. The hammer is also held down by the bolt when in the rearward position. Action open, safety on is the standard "weapon clear" drill. No, no way.
A subterranean chamber is a room or open space that is underground.
Many internet windows and programs will have different buttons to manage the open windows. Buttons may include a file, edit, refresh, bookmarks, and tools windows.
Loading a pump-action shotgun is fairly simple. Open the action and hold the stock underneath your arm. Pop a shell into the action, then close the action to load your chamber. To load the magazine tube, take the next shell and push it into the action, then pin it in place using your index finger.
You can't enter the Chamber, you can only open the entrance.
Open the covers and snap out the old buttons and snap in the new ones. You pry them off with a small screwdriver. Open the covers and snap out the old buttons and snap in the new ones. You pry them off with a small screwdriver.
