I am new to reloading. I actually bought all my equipment in November 09. I have yet to reload my first round. Just reading and learning right now. I have three manuals right now Hornady, Lyman and Nosler. My question is why does Nosler only give the maximum C.O.L. I am going to try to load a 150 grain partition spitzer in 30.06. Can I use the specs for the 150 grain (C.O.L.) in the Lyman and or Hornady manuals. Max is 3.34 in Nosler which is all the Nosler manual gives and 3.23 C.O.L in Lyman and Hornady. May be petty but I want to be safe. Thanks for your input in advanced.
