With the first shot from a clean barrel you shouldn't have any problem seating the ball. You will feel it hit the powder charge and start to crunch the powder. You don't want to crush the powder, just seat the ball firmly on top of it. After loading the first rd. it is a good idea to take a piece of electrical tape and run it around the ramrod flush with the muzzle. This will let you know that you have the ball all the way down for the next loading. Of course if you change the amount of powder the mark will be in a different location. Once you have worked up the load you plan to stick with, you can scribe a shallow mark around the rod with a sharp knife.
