I shoot that 200 grain 10mm/40 caliber XTP/MAG and had great success and accuracy w/it. But when I look at the XTP beside the lehigh , and the length of it I am wondering if the flight will be more stabil for an accuracy increase if that is possible? I am real happy w/ the 200 grain 10mm/40 caliber. Also note I was shooting 110 grains measured of BH209, is that what you will be testing with?
