I'd personally look at the 155 scenar mate 45.5 grains of wildbore in my armalon was getting 2880 could have easily gone higher than that but it was so consistent last time out with maggot it was one hoping for 5 rounds @200. I played with every bullet weight from 155-210 in the 308 and unless it's an uber special set up I came to the conclusion that 155 is optimal
