Here's a question for you all. I got into a debate with someone in another forum who offered a collective of loading data for .45 ACP all his data gave starting charges for given bullets and powder, but no Max. He stated: "Here is a compilation of ALL data I have found in various reloading manuals or published in magazines. Note that there is no such thing as a max load that is a max load for everyone. I start at the lowest starting load and work up carefully." My interpretation of the statement and data is for me and for most people that without a known given Maximum charge it is useless. That though I agree every published resources for given powders and bullet combos, Max may be different... you need to have a reference (of course cross checked) in order to stay safe and stay within specifically safe pressure ranges. In other words... if I gave anyone here a given starting charge and said "work up carefully" would you be OK not knowing a max charge for a specific powder?
