Sidelock: I don't use a scale at all. I wouldn't want to carry one to the range, much less into the field. If you read my prior post, you would not have asked the question.
The reason I don't use a scale is because I knew this was not how it was done ages ago, and that there had to be a way to get consistency without crushing powder. In my flinters, I just touch the powder, and eventually mark my ramrod so I can just load to the mark. With Percussion, I hold the barrel vertical, so that my barrel becomes a long drop tube, and that compacts my FFFg powder just fine. Because I don't use a scale, and I don't want to deform a ball I have worked so hard to mold, weigh, sort, and carry to the range, I seat it gently onto the powder, and get fine accuracy out of the gun. I did have to round the crown some more on one Percussion rifle because the edges were cutting my patches, and nicking the balls. But, once I rounded those edges, my accuracy went up dramatically. I think it is Mark Lewis who was always recommending using a thicker patch, and smaller diameter ball on the forum here. He had a point about that, within reason.
The boys who are constantly talking about using a thin patch and tight ball are taking their cues from the 1880s target shooters, who introduced the false muzzle, and conical bullets to muzzle loaders, and perfected accuracy using tight patching, and ball combinations. In the Chunk gun shooting game today, we see men using ' Teflon " patches, oversize balls which, when driven into the barrels become elongated bullets with round noses and round bottoms, still in that near indestructable teflon patch. They are not really shooting a PRB any more, but a conical bullet in a synthetic patch material. They increase the velocities to over 2000 fps, which you normally could not do with a PRB, and shoot very small groups at 60 yds, well before their loads come down in velocity to get near the transonic barrier. If those same loads were fired at 100 yds, or 150 yds, they would not be as accurate as they seem to be at the shorter ranges. But that is the game that is played.
FWIW, a ramrod got its name when muskets were given steel ramrods, to immitate those used to load cannons, with a fat wide button on the working end of the rod. The round ball, and later the minie ball, were undersized purposely, and the " Ramming" was intended to help upset the pure lead ball so it filled the diameter of the smoothbore musket into which it was loaded. Ramming the ball home was required because there was no way to clean the bores between shots, and residue quickly built up in these muskets, making it difficult to seat a ball on the powder even with the full force of a man's arm as he Rammed the ramrod on the ball to get it past the crud.
There is no reason in using these historical factors to justify using a ramrod that way with a rifled barrel, or for that matter, with a smoothbore. You are not in a battle with the gun, so you have the time to clean between shots. You can make or buy balls that are closer to the diameter of the bore, and you can test various fabrics to find one that is the right thickness of patching for your gunbarrel.We have loading rods with jags made to hold cleaning patches, wonderful lubes, spit, and just plain water, or alcohol to use to clean that barrel and maintain the firearm properly. Those British regulars, and Hessian mercenaries did not have those luxuries. And they were fighting for their lives, thousands of miles from home. Different rules apply. Bouncing a ramrod on a ball does nothing but distort the face of the ball, decreasing potential accuracy, but worse, because you can't deface the balls the same shot after shot, you create a factor for eratic shooting that was not present when you sorted the balls by weight and appearance before loading. I knew one man who showed me his ramrod would go down in the barrel about 1/8" by bouncing it 2 or 3 times, and he claimed this was needed to seat the ball on the powder. After looking at the jag on the end of the rod, I was convinced he had just flattened the RB out that much, and hadn't moved the ball any at all. We later found out that because he did not clean between shots, he had a ring of residue that built up just where the ball seated in the barrel, and it was this ring that he was having to push past to reach his mark. His balls were flattened, and his accuracy, even from a bench, was lousy! We got him to clean between shots, stop bouncing that ramrod on the ball, and he had no more problems loading to the mark, and his groups began to shrink immediately.
Instead of pursuing these folk forms, go to a large shooting match, find out from older shooters- you know the guys with all those annual badges or pins on their hats showing how many of these shoots they have attended- who are the best shooters. Then go and watch the top 5 or 10 shooters load their guns and shoot. Pay attention to what they do and what they don't do. Talk to them about why they don't do something you were told to do. Ask them why they do something differently. Do this between matches, so you don't interrupt their loading procedure. Nobody wants to dryball a gun at a major match!
