Just my limited experience resizing brass/hulls. On some of them I have to resize in 2 steps, basically a beginning one and then the final one. If I try to use certain hulls in the final resizing without doing the first partial resizing it will crumple the brass. I also think whatever type of lubricants you use probably plays a part in how easy your resizing goes. I would take a digital caliper and measure inside the chamber then measure your unsized brass shells to see what the difference comes out to.
