my 40-65 is straight tapered & reformed from 45-70 cases ( I wonder how much if any difference there is between the two ??? ) my expander works nice with my lubrisized bullets... sounds like your expander is big, or your bullets ( if you're buying them ) are too small... how have your groups been with the loose in case bullets ??? reason I ask, is curious if they are also loose in your bore... if so, try finding a bigger diameter bullet... if they are fine in the bore, maube you can find a smaller expander button ???

what brand dies are you using ??? what bullet diameter ???
