Another item of note about the sabots. I trie both the crush rib black and the smooth black Mag Express sabots. My gun with the .452 XTP Mag bullet would only group well with the black crush rib sabots. The Mag Express smooth black sabots were all over the place at 100 yards. The Mag Express sabots and bullet were a tight fit in the barrel where as the crush rib were snug but slid down the barrel easy even after shooting. Just thought I would relay that bit of info. I did not expect that much difference in groupings from different sabots.
