If I use Hornady bullets, I'll use Hornady data. Same with Sierra, Speer, etc. If I load lead bullets I use Lyman's Cast Bullet Handbook.
FWIW; I pay very little attention to any forum "expert", web blog, Range Rat, or Gun Shop Guru. I've heard, at the range or from some sporting goods counter man, some really wild stuff concerning powders/loads, etc., and I've seen a couple wild (mebbe dangerous) loads listed on a forum, and I just take it with a grain of Bullseye. I have several manuals that have enough info/load data to last me the rest of my reloading life and I trust their suggestions. I've been reloading since '86 (first try was with a Lee loader in 1969, only reloaded a few hundred, divorce interrupted shooting/reloading), and have an idea how to reload safely...
