[QUOTE="Bart B, post: 616359, member: 5302"] A ladder test is simply loading a batch of cartridges with each ones powder charge a few tenths of a grain heavier than the last one. Then each is shot at a long range. At some point the drop of 2 or 3 consecutive shots will be closer together vertically. That often indicates a good charge range to test several shots with. Why? Because the muzzle velocity spread between shots is lowest for those few. Note this works best for super accurate rifles fired by people who are excellent marksmen. The worse a rifle's accuracy is along with poor marksmanship skills, the less reliable the data is. [/QUOTE]
