This will guarantee a long life of your shotgun’s barrel and reliable work of all parts.

Gun Safety (Blown Remington 870 Barrel)

It is important to remember that all firearms are potentially dangerous.

Remember: if you experience a flat report or low recoil, stop shooting immediately and check barrel for an obstruction. If the gun fails to fire when trigger is pulled wait 30 seconds before unloading and keep pointed in a safe direction(you may experience a “hang” fire and the cartridge will go off after a pause).

If you think that a bullet, birdshot, buckshot or anything else is obstructing the barrel, immediately unload the firearm, disassemble it and check barrels. It is not sufficient to look in the chamber only.

If there is a snow in your barrel, do not shoot, clean your barrel first.

If you use reloaded ammo be very careful because it is more dangerous than the new ammo. Be very careful when reloading ammo and be sure to check everything twice.

Here are several photos which show what can happen to your shotgun’s barrel when shooting with obstruction inside:

Here is what happened in this case: the owner of this shotgun had one reloaded shell with no gun powder inside and the bullet haven’t come out of the barrel. When he fired it for the second time, the barrel was blown out.
