Unfortunately a great section seems to have been lost in one of the updates.
We used to have a section with helpful stuff, all locked threads, for easy reference. One was Stumpkiller's recipes.
There was a chart for pure lead round ball weight by diameter. Another for comparison of grains to drams to ounces by volume. There was even one with directions and a pattern for making a shot pouch. I think there was one for balls to the pound and bore diameter.
And many more.
