Tried searching, hopefully I'm not beating a dead horse.
As I understand it the idea of the ladder test is to show you what "zone" of charge weight gives the most flexibility in charge weights, by indicating bullets that left the muzzle while it was at the top or bottom of its whip.
Thus, you are looking for vertical dispersion based on muzzle velocity - which 100 yards won't readily show...but also grouping of somewhat dissimilar muzzle velocities (because barrel whip is more influential than a handful of FPS????). So, I would expect a ladder test at say, 600 yards to dull the obviousness of the "grouping" I'm looking for...?
I can perform the test at 200,300,400,500, or 600 yards. My club has pits, so I can even have my pit bitch pull my target and mark it after each shot.
So - what yard line ought I shoot from?
