Trefningen ved Majadahonda
En britisk-portugisisk kavaleristyrke barket sammen med en fransk kavaleridivisjon ved Majadahonda i Spania. Begge sider hadde rundt 2000 mann, og både den franske og britisk-portugisiske styrken mistet rundt 200 soldater. Selve slaget, som var en del av den spanske selvstendighetskrigen, endte uavgjort.

With the technique called lead lapping pitted or damaged rifle or pistol barrels can have new life. In short, the process involves casting a lead slug into the barrel. Apply abrasive to the slug (or lap) and work it back and forth in the barrel until the bore is polished.

The patched roundball is said to be an early American invention, if it's right I don't know. It was used in the American woods from around 1740, probably a little earlier. The principle behind the patched roundball is simple: By wrapping the undersized roundball in a piece of greased cloth and then forcing it down the barrel the problem of loading a rifle without hammering the bullet down the bore was solved. The patch was as mentioned greased, often with bear fat. The fat helped keeping the fouling soft, which also made the loading easier. The most common patching material was linen or cotton which had to be tightly woven to survive the travel up and down the bore. Some will claim that leather (buckskin) was used as patching, but I doubt that was very common. Leather was too costly for a hunter or farmer to be shot out of a rifle.

Loading a Rifled Muzzleloader with Roundball
The things you need are:
- A muzzleloading rifle with flint or percussion ignition.
- Black powder and caps (or flints if it's a flintlock.)
- Some roundballs.
- Linen or cotton patches. Denim is good too.
- Bullet lube. Some people use saliva.
- A bullet starter.
The thickness of the patch is determined by the relationship between the groove diameter of the rifle and the roundball you are using. Let's say you are using a .50 cal. rifle who's groove diameter is .509". The bullet you are using has a diameter of .495". By calculating it as follows you can get an idea of how thick the patching should be: Groove diameter: .531" minus ball diameter : .495" = .036" i difference. Now we can divide .036" in two and minimum thickness will be .018". (There will be cloth on both sides of the bullet, that's why we divide it by two). The thickness of the patches and the bullet diameter can be measured with a micrometer.
The process of loading
1. Make sure that the barrel is dry, run a few dry patches up and down the bore. (Never run a dry patch down a bore with fouling in it or it will get badly stuck down there.) Snap off a few caps if it is a percussion gun. This dries/burns up any remaining oil in the nipple.
2. Measure or weigh up a suitable charge and pour it down the barrel. A rule of thumb is 50 grains for .50 cal. rifle, 45 grains for a .45 cal. and so on. Keep your face away from the muzzle in case the charge ignites.
3. Place a greased patch over the muzzle.
4. Place a roundball on the patch and center it. Push it down with the thumb until it is flush with the muzzle, or as far as you get it. Tight fitting combinations can be hard to push with the thumb.
5. Take your starter and place it on the ball as shown below. Give it a quick thump.
6. Do the same thing with the long rod on the starter. See illustration below.
7. Take your ramrod and gently push the ball down the bore until it is seated against the powder. There should be no air gap between the ball and powder. That could make the barrel blow up. See below. Again, remember to keep your face away from the muzzle, the gun is now loaded. Also remember to keep the muzzle in a safe direction at all times!
8. Remove the ramrod from the barrel.
9. Cap the rifle if it is a percussion or prime it with priming powder if it is a flintlock.
10. Cock the hammer and fire!
