There are some variables to consider. Depending, you may not need to size at all. Your alloy will effect the final diameter as dropped from the mold, and the molds themselves are sometimes off a thousands or two. I would not consider purchasing sizing dies until after it was determined they are need or not. The advice about +.002 over bore is sound. I will go out to .003 with no ill effects if it means avoiding sizing.
