Slaget ved Palikao
Slaget ved Palikao ble utkjempet under den andre opiumskrigen mellom en engelsk-fransk styrke og Qing-dynastiet i Kina. Kineserne mønstret 50 000 mann, mens de vestlige kun hadde 10 000 under våpen. De vestlige styrkene seiret likevel, og kunne nå marsjere inn i Beijing – noe som markerte slutten på Qing-imperiet.

From time to time new black powder equipment surfaces which is marketed almost as revolutionary. Most often it turns out that the product does not keep to its promises. One of the products that have received much publicity in later years is called \'Lehigh Valley Patch Lubricant\'.

You can learn more about the history and use of the rifle musket and Minié ball in the brand new book From Musket to Metallic Cartridge: A Practical History of Black Powder Firearms.
Most original muskets have a special progressive depth rifling. The grooves were deeper at the breech area and became shallower towards the muzzle. Usually .015" deep in the breech and .005" towards the muzzle. Unfortunately, very few replica musket manufacturers rifle their musket barrels this way today. Parker Hale in Birmingham, England made Enfield replicas with progressive depth rifling, but the machinery is now sold to Italy. I don't know if the quality of the Italian replicas are as good as the Birmingham Parker Hales.
If you have a "normal" replica rifle musket you should be able to put 5 shots in a 1,5" group at 100 yards. You should then pick a bullet that is about .002-.001" under the land diameter of the barrel. I'll use my Armi Sport .58 calibre 1861 Springfield musket as an example: It measured .581" across the lands. Then I had to have a minié bullet that had a .580" diameter. You'll notice that most of the moulds available has a diameter that ranges from .575" to .578". If you need a larger diameter you'll have to special order a largerr one or somehow enlarge the cavity.Finding the Right Powder Charge
If you have a minié ball of the right diameter you're on your way to get some acceptable accuracy. Warning: the work of finding the best charge could take ages! A charge of 55 grains can shoot great while a 56 or 54 grains charge can open the group considerably. I use to start with a low charge and build my way up with a .5 grain increasement. 2F or 3F? Well, it all depends on what your musket likes. The original US charge was about 60 grains black powder and the UK Enfield charge was 70 grains. I have never experienced that a musket has performed well with at normal minié bullet with charges over 80 grains. The reason for this is that the skirts get blown which affects accuracy. Start some place in the 35 grains range with 3F and 40 grains for 2F. It could take some time before you get the 1,5" group at 100 yards, but at he end it's worth it. Shoot from a bench rest and remember that it doesn't matter where on the paper the bullets hit as long as they are grouped. Sights can be adjusted later. I prefer to start the shooting at 100 yards because some loads will shot great at 50 yards but lousy at 100. Never a problem the opposite way though. Another important factor to consider is the bullet lube. It's purpose is to keep the fouling soft and lubricate the bore. Tallow and bees wax was the original lube, and that also works ok today. My Springfield shoots best with T/C Bore Butter. It is kind of sticky and slick, but I have not found anything that works better. If the fouling gets hard it is about time to consider a new lube. I use to feel with a finger in the bore after each shot, and then the fouling should be soft. On hot, dry days har fouling could be a problem, but if you wait a little longer between each shot it should work itself out. Some like to put grease in the base of the bullet, some do not like it. I prefer lube in the base, but not a single gun likes the same thing it seems. Here are 5 points that you should follow to get the best accuracy with a minié ball:- Weigh your bullets to +/- one half grain.
- Weigh your powder to +/- .1 grain.
- Be consistent in what you're doing. Do everything exactly the same.
- Use powder and caps from the same lot.
- Cast your bullets from pure lead.
