I have read a lot of posts about working up the most accurate load for a rifle, but what is the best way to do it? Do you start with one ball size and change powder charges until you find the most accurate and then change patch sizes? Do you change ball sizes with the same powder load and patch and then change powder loads? I understand what I am trying to do, I'm just wondering if there is a quicker way to get there. Right now, I'm shooting 70 grains of 3f Goex, 0.530" balls, and a 0.018" patch lubed with bore butter out of a .54 TC Hawken (I don't know the model). I am fairly happy with the way this combination groups, but I wonder if I can do any better. I was given this rifle a year ago by my father-in-law, and that was the load he always used, so that is what I have been shooting. Any suggestions on load development method will be greatly appreciated.

How do you work up a good load?

The easiest thing to change is the powder amount, the hardest is the ball size. I usually start out with something near where I want to be for killing a whitetail at "normal" distances, 80 yards +/-.
I slice my patches at the muzzle or loading block, so I'll buy five or six yards of cotton tick material at a time. I usually have a supply of 0.010", 0.015/.017" and 0.018/.020" on hand. My experience is the thicker the patch, the better the accuracy.
Lube is mostly a matter of convenience for me. Liquid lubes, as a rule, are more accurate, but I don't like futzing with bottles. Wax/grease lubes are easier, but can have inconsistant results from build-up or variations in lubing that can cause stringing & c. Lately, I have been dipping strips of patching in liquid lube and letting them dry overnight, then repeating. These are fast & simple to use and carry, and if I wipe with a spit patch every fifth shot I can toot away all day with good accuracy.
I'll start with a ball 0.010" under bore size (.530" for a .54) and begin with a load that is upper middle for powder, say 90 gr FFg for the .54. I shoot five shot groups at 25 yards. After a sampling of these, I'll up the powder 5 grs, shoot a few more groups, then lower the powder to 85 grs or so and repeat. Depending which gives better results, I'll then try 2 grs up and down from that level.
My past favorites have been 90 grs FFg in a .54 and 84 gr in a .50 I own. Currently working up a load for a new .54 flinter.
Once I get the main big-game charge where I like it and sighted in to be 2" high at 50 yards, I play around with half that amount of powder at 25 yards until I find a load that shoots point-of-aim. This becomes my small-game load.

I don't believe that there is any wrong way to do it, it's just that it's easier to work with the materials that you already have on hand. The easiest thing to change is the powder charge. There is sometimes a noticiable accuracy difference between hunting loads and target loads, even from the same rifle. Target loads are usually weaker and designed for paper target accuracy. The rule of thumb is to begin with 1 grain of powder by volume for every caliber (.54), then working up incrementally. If you don't notice any better results with a weaker powder charge, then it's time to experiment to see what works. You might try a .015 patch next, or another powder, then another ball size, etc...(You may even want to try the same size balls from another manufacturer.)
I would suggest to experiment with the intention of determining the best accuracy you can obtain with these balls before moving on to another size, since the .535 balls will probably require thinner patches and may also be tighter to load.
Lastly, try to ram with consistant pressure on the ball when seating it. Firm, but not too much or too little. This is just another variable to try out along with everything else. :hatsoff:

The only other thing I could add, is keep a journal. Record temp, date and time, powder load, projectile, patch, powder type, wind, distance, ect... what ever you think is important. 60 days from now you will not remember where you started, so it'll be harder to see where you are going. :shocking:

HOW TO: Work Up A Black Powder Load

I have been shooting black powder guns for longer than I care to admit. The one question that I have heard repeatedly is, "What is the best load for my gun?" If you hang around black powder shooters for any length of time you will find that there are more answers to that question than grains in a can of powder. Or as my side kick likes to say, "It depends." So if it depends, then perhaps I can help with what it depends on. The first thing that it depends upon is whether you are target shooting, and this includes plinking, or hunting. The difference is really obvious. You never have to worry about a target running off, and targets taste terrible no matter how you cook them.
Let's start with target shooting, we'll cover hunting in another article. Now the objective to target shooting is to produce the tightest group possible. Notice I said group and I did not mention score. You tighten up the group and the score will come with it. In fact there is a primitive match where the winner is determined by the tightest group. There are four components to every black powder load, the powder, the patch, the lubricant and the ball. Varying any one of these can greatly affect your group. Let's assume that you have a new .50 caliber percussion rifle. You've picked this rifle because the caliber is suitable for target shooting, plinking and hunting deer sized animals. Your first decision is what caliber ball to pick. With a modern gun the manufacturer will usually recommend a caliber. This is a good place to start. With a custom gun or such, measure the bore with a caliper and select a caliber about .005" less than the bore measurement.
Now I am assuming that you already have a safe place to shoot, a comfortable bench to shoot from and, the gun will at least print on paper. If you are an excellent shot and never miss then you can skip the bench. I have only met one person like that and she out shot me all day long. The first thing you want to do is wipe the barrel and then fire a couple of caps, muzzle pointed to the ground, to clear any oil from the barrel. Next you must decide how much powder to use. For target shooting the best bet is to start low and work your way up. I'd recommend a starting charge of 45-50 grains for a fifty caliber. Yes I know it's light, but I have never had to a shoot an angry charging target. This is a starting load. Your next step is to select a patch and lubricant. I'd start with a .010 or .015 patch. Use cotton material only. Save the exotic stuff for the idiot down the road. Lubricate the patch, start the ball and patch down the bore and seat them with your ram rod. My lubricant of choice is spit. Works good but at times the patches taste terrible. Kind makes you wonder where they've been. One thing about spit, it's tough to run out of.
Okay, now you're ready to shoot. Before you shoot, remember, you're not interested in anything but your group. If you're on the paper, your doing fine. After each shot wipe the bore with a damp patch, then a dry patch. When you reload, try to seat the ball with the same pressure each time. Make sure the ball is seated on the powder. (A marked ram rod is handy for this.) Don't beat the ball into the powder, just seat it firmly. After shooting five good shots that means no flinching, eyes open, etc., collect your target.
Here is where the fun begins. By varying your load, patch, and lubricant you can adjust your group size. Some guns shoot best with tight patches and grease lubes, other do better with looser patches, spit lube or lighter loads. The secret to success is to experiment and be consistent. Now I can help guide you on some of this, but the rest you have to do yourself. In my experience most black powder guns do well with a snug patch and ball combination. Snug is when the ball and patch can be started by hitting your ball starter with a sharp smack from your open palm. If you're a lady, a light tap from a plastic hammer head. If you have to beat the ball and patch in, then your deforming the ball. A good way to judge is to retrieve your patch, although this nearly impossible at a well-used range. Look for cuts in the patch, a sure sign that the patch is too tight. Also look for burned edges, a sign that the patch was too loose. Anything in between is good.
I always start by varying my powder load, usually in five grain increments. I like to shoot five to eight shot groups. After each group I remove the target and mark the load, patch, lubricant on the target. These become my reference points and records. Ideally as you work through heavier loads, you will see your group tighten up and then widen. Sometimes you have to try lighter loads, but usually it works the other way. When you get to the point where the group widens, then the previous load was the best. Shoot another group at the best load to verify your assumptions. By the way I have never had a target charge greater that 70 grains in a .50 caliber rifle. If the gun has a lot of recoil then your way too heavy. Lighten the load.
After I have determined the powder charge, I start varying the patch and ball combination. Depending upon how tight the original combination was, I might try slightly heavier patch material or a different type. Sometimes a pillow tick seems to work better than straight patch material. If I see an improvement, using my best powder load, then I try a lighter patch and slightly large ball. Or at times I go the other way. Each gun is different. Finally I vary the lubricant. Remember always try to remain consistent and keep a record.
Working up a load is an easy but time consuming process. Of course and trip to the range is better than yard work. It may take several trips to the range to get close and a lot more to get the ultimate group. But with your gun holding a 3/4" group at 25 yards you'll be one step closer to that 50-xx score.
