Not trying to be a smart alec but you should consider that reloading for most of us who aren't obsessed with chronographs and pressure test equipment is more like baking a cake by the book than it is like experimentation. Tried and true loads from a powder or munitions company and of tested and verified performance, learning your equipment and components so that you aren't distracted from care and safety in the duplication of those loads, and subjective assessment of their performance on the quarry or target sport of your choice is chore enuf without the "experimentation".
