Simón Bolívar invaderte Venezuela
Den sør-amerikanske uavhengighetslederen Simón Bolívar gikk inn i Mérida i spissen for invasjonen av Venezuela. Han ble utropt til folkets befrier og inntok Caracas den 6. august. To dager senere erklærte han Venezuelas andre republikk.
Etter utallige stridigheter måtte Bolívar flykte og fikk i 1815 beskyttelse på Jamaica. I 1817 vendte han med haitisk hjelp tilbake for å fortsette kampen. I 1819 lyktes han i å befri Venezuela. Deretter marsjerte han over fjellene til Colombia og beseiret spanjolene også der, hvoretter han proklamerte opprettelsen av republikken Gran Colombia (Colombia, Venezuela, Panama og Ecuador), med ham selv som president. Målet var likevel å befri hele Sør-Amerika fra spanjolenes åk.
I 1823 tok Bolívar kommandoen over invasjonen av Peru, og i september kom han til Lima med general Sucre. Den 6. august 1824 beseiret de sammen den spanske hær i slaget ved Junin. Den 9. desember tok Sucre den siste spanske befestning i slaget ved Ayacucho, og det spanske styre i Sør-Amerika var dermed opphørt.

The flint and percussion locks are the most commonly used ignition systems used in today\'s black powder firearms. Other systems, such as matchlock, snaphaunce and wheellock are also used, but in more limited quantities. This article gives you a brief overview of the different systems.

Why were paper patched bullets popular in the late 1800s? First of all, they were easy to mass produce with swages compared to the grooved bullets. Secondly, many used them because of the idea that leading was eliminated, or at least reduced to a minimum. Paper patched bullets were used civilians and armed forces all over the world. When the Norwegian Army started using metallic cartridges in 1867, a grease grooved bullet was used in the 12 mm Remington rolling block ammunition. However, when the Jarmann rifle was adopted in the early 1880s a paper patched bullet was introduced. The Norwegian Army also used a paper patched bullet in the Nagant revolver ammunition. Paper patched bullets were especially popular in Europe, and was used in, for example, the British Martini-Henry rifle and Mauser's Infanterie-Gewehr Mod. 71/84. From a military perspective, the paper patched bullets were not that popular in the USA, but they were extensively used among civilians. The use of paper patched bullets is especially known from the buffalo hunts on the American prairies where millions of the shaggy beasts fell for paper patched bullets. In my opinion, paper patched bullets was a kind of "fashion" in the early black powder cartridge era, and they were not necessarily better compared to grease grooved bullets.
What do I need to paper patch bullets?
I addition to the usual remedies you use when loading black powder cartridge ammunition with grease grooved bullets, you need a bullet mould that throws smooth sided bullets, or store bought smooth sided bullets. You can also paper patch grease grooved bullets. If you're going to use grease cookies you should have a plan on how to make them. I use a Lee Shaver lube ribbon extruder for my lubrisizer that goes into a regular .45 calibre the sizing die. You also need proper paper. More on this later.
A good cleaning or wiping rod is important, because paper patching involves a lot of cleaning. Several qualities are important for a good cleaning rod. It must be flexible, it must be in a material that doesn't wear the bore and it must be simple to use. My favourite is Tipton's 1-Piece Deluxe Cleaning Rod with an ergonomically designed handle that spins on two sets of ball bearings – the result is that it smoothly follows the rifling both pushing and pulling, even while under pressure. It is made of carbon fibre, and has all the characteristics that are described above. I prefer using jags, but several of the world's best shooters use a nylon brush instead of a jag. The nylon brush is used the same way as a jag.
Some shooters use a taper crimp die to secure the bullet into the case. A standard roll crimp will damage the paper and should be avoided. The difference between a taper crimp and roll crimp is that a taper crimp squeezes the ends of the case mouth inward along the side of the bullet but does not engrave the bullet, while a roll crimp is a slight inward roll of the cartridge case into the bullet.
Paper, bullet and brass selection
It may be a good idea to think about what diameter you want for the finished paper patched bullet. There are two schools within paper patching business: Those who patch to bore diameter and those who patch to groove diameter. Most people seem to prefer the first method. An advantage with bore diameter patching is that you can seat the bullet far out of the case since it isn't stopped by the rifling – which also enables you to add more powder into the case. Groove diameter patching is a good idea if you don't plan to wipe between shots.
Finding the correct diameter for a bore diameter bullet: My .45 calibre Shiloh Sharps has a bore diameter of .450", and a groove diameter of .458". A good starting point would then be to paper patch the bullet to about .450"-.452". You should test different diameters though – what works in some rifles does not work in others.
Finding the correct diameter for a groove diameter bullet: Using the rifle above, you should paper patch the bullet to about .458".
25 % rag content paper is often recommended, but it seems like good accuracy can be achieved with many kinds of paper. I have used Eaton's 9 lbs. Air Mail Paper, and a paper from Buffalo Arms with 100% rag content. A thin paper that works really well is a sketch paper marked 55W produced by Seth Cole.
For .45-70 I use a bullet mould made by Buffalo Arms that throws a .446" diameter 535 grain bullet that I patch to .451" with the Seth Cole paper. If I use a thicker paper I size the bullet to .444". In my 10.15 mm Jarmann rifle I have used store bought swaged bullets similar to the original bullets that I size to .401" and patch with two wraps of Eaton's 9 lbs. Airmail Paper to .407". Bullets for paper patching should be cast or swaged from a tin alloy because the tin adds hardness. 1 part tin and 30 parts lead works ok, but some will claim it is too soft. 1:20 and 1:16 are examples of other tried and tested alloys. I have used 1:25 myself with success.
I prefer thick walled cases. This is because the diameter of the bullets is smaller compared to grease grooved bullets and thick walled cases hold the bullets better. In .45-70 I use Remington brass since they have thicker walls compared to, for example, Winchester and Starline brass.
Making the paper template
It is important to patch the paper around the entire bearing surface of the bullet – if not you will have leading in the bore. The most common is to use two wraps. Before patching, it is common to moisten the paper in water – for example on a wet sponge. It is also ok to dry patch, but it may be a bit more difficult.
Wrap the paper tightly around the bullet. The remaining paper is tucked under the bullet base. When finished, set the bullet aside to dry. I have found that .45 calibre bullets fit perfectly in ammunition boxes for handgun ammunition.
Between the bullet and the powder it is necessary to use some kind of wad to prevent the powder gases from burning the paper. I use a .060" thick cardboard wad. For lubrication you can use a grease cookie, but make sure you have a cardboard or felt wad under and over the grease cookie. If you load hunting ammunition grease cookies are often necessary as you don't have time to wipe between shots. The grease cookie lubricates the bore, softens the black powder fouling and enables you to shoot a couple of shots before having to wipe the bore. Dirty bores and paper patched bullets usually means poor accuracy. For target shooting most – if not all – shooters wipe between shots. This means that grease cookies are superfluous, but they may help soften the fouling and ease the cleaning.
I don't lubricate the bullets, but I know some shooters rub the paper with a thin layer of bullet lube. I don't like lubed paper patched bullets, because they tend to collect dust and grit which wears the bore.
As mentioned above, use a taper crimp die as roll crimp dies may damage the paper. Actually, you don't have to crimp the bullet at all; it doesn't matter if the bullet is seated loosely in the case.
When cleaning between shots it is important to be consistent in everything you do, and that you use the same wiping technique for each shot. Start with a patch moistened with soapy water, black powder solvent, a water soluble oil/water mix or similar. I guess pure water works as well. Depending on the weather conditions and air moisture I usually use two moist patches followed by a clean and dry.
In my early paper patch career I cared about how the paper looked after firing and tried to interpret my findings. Now I concentrate on the target instead. If I consistently get good groups it does not matter how the paper looks. When I shoot my Shiloh Sharps I usually don't find paper at all – except for the paper that is tucked behind the base of the bullet. The rest of the paper is probably shredded to confetti as it exits the muzzle, and that does not have to be a bad sign. It is important that the paper is separated from the bullet as soon as possible to prevent it from disturbing its flight on its way to the target.
What about the accuracy? If you are lucky, paper patched bullets can shoot just as good as, or even better than, grease grooved bullets. My Jarmann rifle actually prefers paper patched bullets, while my Shiloh Sharps shoots equally well with paper patched and grease grooved bullets. Because of the wiping involved with paper patched bullets, I usually use grease groove bullets for competition. I don't wipe between shots with the latter.
As you see from the below video, it takes about 90 seconds to shoot a paper patched cartridge and cleaning it with three patches afterwards.
