I'm not putting down Lee, I like Lee products. All my handgun dies are Lee, I have several Lee Collet dies and all my molds are Lee. I'm just saying Lee data is not their own.
I quote from the first page of "Modern Reloading" 2nd Ed.
" Comprehensive load data, compiled from all the major powder suppliers published information, sorted in logical cartridge, bullet weight, and velocity order"
