I am getting ready to order some powder from Graf's and want to check out one of the new powders for the .308 Win. What powder is recommended for the 168/175 gr bullets now. I used the old style of IMR 4895 and 4064 for the past 15 years and I have played with Benchmark and 168 gr lately. With the new powders on the market I am seeing some impressive speeds on here. What is the accuracy like with these new powders? I am looking at RL17, Power Pro 2000 and 3000, or any other recommendations.
