Ordered a .459" case expander and die body as well; should really help to lessen the paper patches that get torn when seating. The RCBS case expander mic'ed at .456" in my set and my PP'ed bullets are .460". "The Paper Jacket" by Paul Mathews is also in stock at TotW for US$21. It's $40+ on Amazon and out of stock almost everywhere else. I borrowed a copy from one of my dads friends and gave it a read a couple years ago and have been meaning to buy my own.
NOE makes some precision expanders that fit on the LEE expander die. The Lee expander die is about $20, and then each NOE expander costs about $5 for each size you want. They work really well.
