I have .270 win imp. and I use 270 weatherby neck sizer die to form cases. I use the standard case length of 270 win- 2.540 in., when I trim the brass. The weatherby die does not crush the expand cases of the 270 improved ,as a standard 270 win die will. Some of the brass you have watch for cracks at the web near the base. I had problems with Federal cases cracking at the web. Winchester and Remington cases , I had no problems. Good Luck
