Loading black powder is about as much an art as it is a science. There are certain laws of physics that are indeed science, but they are used in conjunction with caution, brains, and experience with each INDIVIDUAL black powder rifle to determine what load shoots best in it. To be able to do that effectively, you need information. Now you can trust your rifle and your life to what some guy tells you on the Internet, or you can get information from reliable sources that print manuals and have pressure guns and ballistic labs available to them. You decide and you pay the price either way. But I tell you straight out and up front that if you don't want to do black powder loading right, you might better take up golf because BP is NOT like loading smokeless powder. It is NOT a progressive burning powder. It is a class "C" EXPLOSIVE and it acts and reacts a LOT differently to various situations than does smokeless powders. If you are confident that the one loading manual you have covers the subject to your complete satisfaction, then I'm happy for you. But you should know that your life could depend on that information and your understanding of it.
The first misconception about black powder is that you can't over load it. WRONG! The first time I ever heard that was a man loading his BP rifle the day before hunting season. It was the first time he had ever done it and the clerk at Wal-Mart told him to load it with a "hand full" of powder and don't worry about it because it would only burn the powder that could be burned in the length of the barrel and all excess powder would simply blow out the end of the barrel.
As the guy was loading his rifle, I went to my truck and got my spinning rod and came back. As the man got ready to shoot his rifle, I asked him if he had ever shot that load before. He said no. Then I suggested that we stick the rifle in the fork of a nearby tree and tie one end of my fishing line to it and back up to pull it to fire the thing. He thought that was a good idea and about six of us standing there all backed up and he jerked the line and shot the rifle. Pieces of it fell all around us and it's a wonder someone wasn't hit by flying parts. It completely blew that barrel off of that rifle into small pieces and split the receiver. You can imagine what would have been the result had he had his face behind that when he pulled the trigger. So much for trusting people you don't know to tell you how to load black powder.
I suggest in the strongest possible way that you read the one manual you have and know all it says about loading black powder. That you state you have already done that and yet come here and ask basic questions about loading techniques would lead any reasonable and prudent person to think that you either don't have a good loading manual or that you have not studied it because if you had a good manual and studied it, you wouldn't have basic questions about how to load.
Okay, I'll get off my soapbox now, but that is my best advice to you as a beginning loader of black powder. Black powder is very unforgiving and you will only make one serious mistake with it and we are going to hear all about it on the 6 O'clock news.
Here's the deal, you need brass, dies, press, BP powder measure, a 24 to 30 inch drop tube, a compression die, dial calipers, and the bullet and load (from a good loading manual) you intend to try. Size the brass, put in new primer, set the powder measure using an accurate scale, throw the change, slowly trickle the powder down the drop tube into the case, put a wad over the powder and push it down as far as you can using finger pressure and maybe a pencil with a soft rubber erasr on the end of it. Using your dial caliper, measure the distance from the top of the wad to the top of the case. Then measure the distance from the base of the bullet you are going to use to the crimp groove on the bullet. Subtracting the distance from the top of the wad to the top of the case from the distance from the bottom of the bullet to the crimp groove is the amount of compression you will have to put on the powder column to seat the bullet to the crimp groove. Compress the powder, insert the bullet and seat it. Check to BE SURE there is no air space between the bottom of the bullet and the powder or wad. You are finished except for test firing to check for accuracy.
Once you insure that the load is reasonably accurate, you can begin to experiment with seating depth always insuring that no air space is present in the load, and with different powder charges always working up slowly and closely observing all the usual signs of building pressure. If you have a chronograph, ( A Chrony is cheap life insurance) the velocity numbers will tell you more about pressure than any visable signs on the brass since velocity is a direct function of pressure i.e., if you observe a jump in velocity, you have a corresponding jump in pressure. That is one of those laws of physics that is science and it works EVERY time.
Using the above outlined approach, you should encounter no situations where you or your equipment is at risk and that is the responsible way to load black powder or smokeless for that matter. Try it and let us know how you do. It's always educational to understand how a load is developed and the steps in accomplishing that. I have learned a lot from other loaders following their process, BUT I was WELL VERSED in the proper way to load BEFORE I considered their approach and I suggest that you consider doing the same.
All the best to you partner.
