[QUOTE="highdrum, post: 1946416, member: 13732"] Was it windy during your ladder? Vertical spread is expected with the ladder, but there is a fair bit of horizontal shift which isn't good and usually indicates the seating depth isn't quite right or there's a problem with inconsistencies, which is usually neck tension causing this horizontal shift. Just because something does well at short range, it not always good out further. In this ladder you see shots 4,6 are left of grouping, I know these two had less neck tension when seating bullets and noted it. All other shots had maybe 2.5" of horizontal, this was shot at 420y. Vertical spreads can be combatted with finding optimal barrel timing/harmonics, but horizontal is fought with neck tension and seating depth. Hell even primer seating depth comes into play.
