Thread: Variables affecting precision

It's not intended as a flow-chart or 'how to' of reloading, but at least suggests where you might get the best 'bang for your buck' when trying to increase precision. I also acknowledge that there will be different perspectives on the relative importance of different variables, however I've based my thoughts on my understanding of the data coming out of large sample testing discussed by Hornady/Litz et.al.

More than happy to be corrected here - I just like diagrams to help me understand concepts, and maybe someone else will find it useful.

Another piece to consider would be handloading equipment quality and consistency of process. It's another area of diminishing returns and mysterious voodoo, as you get the pareto 80 with a cheap press, mass market dies, and thrown charges.
