I just bought 100 hp/xtp 250gr bullets and I got tc shockwave sabots,harvester .452 under 300gr sabots, and HORNADY SABOTS 50cal (.452) HIGH-VELOCITY 50/BX.....putting in the bullets I noticed the harvester's seemed to fit the best to the bullet (seated best)...the hornady sabots were taller than the harvester ones.......and looking at the package of the hornady they said they were for .240 xtpmag and 300xtpmag,....I have some 300gr xtpmag bullets and there .452 im not sure what difference would be fit wise....anyone out there shooting 250gr hp/xtps and have a favorite sabot , I'd love to hear what everyone thinks
