Using the Barnes 100gr TTSX, I've tried 7828, Magnum, H1000, and Retumbo. In a SS Vanguard MOA. Best accuracy with H1000 and Retumbo but Retumbo is slightly faster. Norma/Weatherby brass, Fed 215 primer. Mule Deer's favorite load uses the 100gr Nosler E-tip and H1000. Search this site to find the exact load. Good luck! Mark and Belle
