I had Harvester send me some samples of both. The crush ribbed was not as snug. There was not really that much of a difference accuracy wise. I liked how the smooth loaded better. My sabots are usually pretty much laying together down range around 25 - 30 feet away. I never tried the tan sabots.Have you ever tried the light blue crushed ribbed In comparison size wise. Just wondering the difference. The groups wasn’t terrible with the tan sabots but not great neither. I don’t like the fact that they were traveling 80+ yards down range. Also with the crushed ribbed sabots the bullets all were hitting 3-4 inches left of the bullets from the tan sabots
