A couple of examples of Audette ladders





For me a ladder is just to find the powder weight charge that will give me the approx. velocity I want to shoot that bullet at. Predicting accuracy nodes is a little like reading tea leaves IMO

Then the tweeking comes with a seating depth test. The seating depth test will identify best grouping, lowest velocity extreme spread and lowest velocity standard deviation. Varying seating depth will vary you velocity by about 10 or 15 fps per every .015" deeper you seat, so you are essentially timing the bullet exit from the muzzle
