I have loaded for 9 different 28 Noslers now. Starting #10 next month. In every single one I have used CCI BR2. With phenominal results in both speeds, ES/SD, and accuracy. RL33, between 3080-3150fps using 195 Berger EOLs. From sub-freezing to 110°. Whoever says they are not enough for the 28 Nosler is incorrect. Ask Ryan Pierce (Piercision) and Eric Goss (Axisworks) what they recommend.
