I am using a Lee six cavity in .401 for a 40 S&W. My reject ratio is extremely high. I get a good fill on both the closest and furthest cavity but the inside 4 cavities are hit or miss - mostly a miss. The bullets are rounding at the base. I have no idea why this is happening because on the same pout cavities 1 and 6 almost always have great results. Any ideas would be helpful because I am almost ready to return back to the 2 cavity?
