[QUOTE="Bart B, post: 722986, member: 5302"] But each shot doesn't represent the center of a group of many shots of that same load. The bigger a many-shot group is for a given load, the least reliable a single shot of that load represents where its center is. Ladder testing is based on the assumption that a single shot represents the center of a many-shot group with that load. I tried a lot of ladder testing a long time ago when it became fashionable for testing loads. Not as good as shooting a single 20-shot group with each load. I don't believe it represents any node in the barrel. Too many barrels of different shapes and lengths I've seen have shot the same lot of ammo into no worse than 3 to 4 inches at 600 yards. None of those barrels had the same "node." [/QUOTE]
