In my rifle the 185 TTSX has consistently been the most accurate. TAC or 8208 XBR have been very accurate (no chrono on the 8208 yet) book loads indicate they should be similar. Have found loads for 210 Scirocco II and 210 Partition that are quite good as well (2000MR and Leverevolution). If I knew I were keeping the ranges down the 210 Partition would be hard to beat.
