Will gun oil ignite when firing shotgun?

[discusser]

Hi. In the owners manual for my shotgun, it says that the chamber and bore should be thoroughly wiped dry of any lubrication before firing.

So, what happens if I don't wipe the chamber and bore "thoroughy dry" before firing? Will my shotgun explode or something?

Thanks.

Firearms cartridges work by sealing the chamber against the pressure.

When the round is fired the casing expands and momentarily sticks to the chamber wall. This seals the chamber, and the bullet or shot has only one way to go....down the barrel.

With lube in the chamber, the case cannot seal against the chamber, and tries to slide backward. This causes chamber pressures to skyrocket.
This causes bad things, from being really hard on the gun, to a "KABOOM".

Lube in the barrel cannot move out of the way of the bullet or shot fast enough.
The round tries to push the lube ahead of it, and if there's too much lube, it can't move out of the way fast enough.
This can cause bad things, from bulging the barrel, causing a ring in the barrel, or a "KABOOM".

In other words, wipe the chamber and bore with a patch before firing.

The oil will burn up from the hot gases. Increased bolt thrust and other problems can occur .But most people use too much oil anyway , only a thin coating is necessary. Of course I don't worry about it since my shotguns all have chrome plated bores !!

Ok. So, I normally keep a light coating inside the barrel to prevent rust. What if I have to grab my shotgun for home defense against intruders. I won't have time to wipe it dry first.

Should I just keep it dry all the time? If I do, will it rust?

Thanks.

When cleaning your gun always run that oily patch down the barrel and chamber when done and then a little bit later, 30 seconds or so, run a dry patch down that barrel a couple of time to clean all excess residue.

You do not have to have a visible coating of oil to protect from rust. Even after the dry patch is run down the barrel there are still deposits of oil that have found their ways into the microscopic nooks and crannys of the barrel. This will prevent rust just fine.

Like everybody else said, don't shoot any firearm that has a visible coating of oil in the barrel as it can cause pressures to skyrocket and then ELKABOOM!!! which in techincal terms would be BAD.

OK. Thanks.

Wow, I didn't know that CLP or other oil in the barrel would make the gun kB!.... tell that to the workhorse 1917 I've fired with the bore nice and wet with CLP.
