I plan on buying a star sizer next month. I bought the group buy lee mold 6 banger in 45 acp. It throws bullets at .454 dia. and has just 1 lube grove.I would like to size nose first and size to .452. The barrel on my 1911 has a grove dia. of .451. So someone please tell me what I need in order to size and lube this bullet. Thanks-seabat0603
