Again, I think you are generally wrong. It's not that they want you to do all the work for them, I think they are usually (there are exceptions, of course...) looking for a nudge in the right direction. Even printed data can be confusing... and looking at the Speer #14 data for your example... that is a 158grn JHP... there are 15 different powders in their data. If you are a noob, how are you supposed to pick one of those using more than a WAG? Considering the lack of components on shelves these days, someone asking what a good powder might be for their 4" 686 isn't a dumb question. Standing at the shelf and looking at one can of H110, and one can of Unique... even though those are both listed in the printed and bound manual, they are 2 very different powders.
