[QUOTE="fiftybmg, post: 1834605, member: 96316"] There is no single authority, rather gather as much data as you can, compare, and that way make informed decisions. Basic check routine : 1. First see what barrel length the load data was assembled for. Use powder data that's as close to actual barrel length as possible. 2. Find the bullet you are using. If you can't find it, find the next heavier bullet, and use that data to start. 3. Try and use the primer quoted in the load data. 4. If the cartridge is not in the book, next book. 5. If none of the books list your powder for a cartridge, it's not the right powder. When doing load development 1. check actual velocity versus published velocity 2. if your actual velocity is less than published, and you are using the same max quantity of powder, stop there. 3. if your actual velocity goes to the max shown in the data, but your powder is still less, stop there. This is called being conservative. Most variations from published load data are due to one or more of : different barrel length, primer, brass headstamp and ambient temperature. We never know what ambient temperature the load data was put together at, another reason to start low and work up if you are in a hot climate. It is possible to safely exceed published load data for certain cartridge / powder / bullet combinations, but unless you understand how, and have the tools to measure the results, don't. [/QUOTE]
