How does the hammer in a gun cause the powder in a round to ignite?

The hammer itself doesn't cause gunpowder to ignite. In modern smokeless powder firearms, it typically works one of two ways. Either the hammer will directly make contact with the rim (in rimfire cartridges) or the primer (in centrefire cartridges), which causes the propellant in either the rim or the primer to ignite. This causes a chain reaction which ignites the gunpowder.
What's more common in modern centrefire firearms is that the hammer will strike a firing pin, and the firing pin will strike the primer.

Can a bullet go off by itself?
No. Something has to make contact with the primer or cause the primer to get really hot. Dropping or hitting a round, or throwing it into a fire can cause it ignite.

What is a round of a gun?
A round is not the same thing as a bullet. A round of ammunition has 4 components. The bullet is the projectile that comes out of the barrel when you pull the trigger, The primer is the component that ignites the powder when it is struck by the firing pin or striker. When the powder is ignited by the primer it burns rapidly which creates expanding gasses that push the bullet out of the barrel. When you combine a case containing the correct amount of powder along with a primer to ignite the powder and a bullet inserted into the case you have a round of ammo. A bullet is not the same thing as ammo. Without the other 3 components a bullet is just a harmless chunk of lead.

What is detonation out of battery?
"In battery" indicates that a rifle is ready to fire, a round is in place and the hammer is cocked."Detonation out of battery" indicates that the round went off before it was supposed to.It could have gone off in the magazine, as it was being chambered, or as the bolt closed.In a revolver, it would mean that a chamber in the cylinder that wasn't lined up with the barrel discharged.Revolvers and multi barrel pistols that are charged with black powder are noted for this.Black powder is concussion sensitive and a chamber can detonate when the chamber next to it was discharged.Putting the wrong ammo in a gun with a tube magazine can also cause this.The primer can be touched off by the point of the round behind it causing all the rounds in the magazine to detonate.
How many grains of powder are in a 40 cal round?
There are a lot of variables involved with the number of grains of powder in any given caliber round. Most importantly are the type of powder and the weight of the bullet. After that is the loader's preference as to the velocity of the round. For example, I load a 155 grain .40 caliber bullet using Ramshot Zip powder for a "light" velocity of about 1050 feet per second using 5.3 - 5.4 grains of powder.
Why did cowboys leave a chamber empty in their pistols?
The way the old revolvers were made, if all the chambers were filled, the hammer would be sitting on a live round. If the pistol fell, or was jarred by riding, it could cause enough force to fire the round, which could be very dangerous!
