powderburns - I am shooting Hornady .45 caliber 240 GR. XTP MAG's in my Traditions LT Pursuit .50 caliber. The bullets came with black sabots. Picked them up at SIR in Winnipeg. Accuracy is good but they are very hard loading. At cayugad's suggestion, I looked at MMP's website. They offer a slightly smaller (.002) black sabot that may solve my loading problems. I plan to order some and try them. Perhaps you may wish to look at their site also.
