Truly you can drive yourself crazy striving for the exact load. But as a hobby, I enjoy tuning each round to squeeze out the best. I end up sometimes chasing my tail, but what the heck, my time, my effort, my money, my guns.
Actually, re-loading is what you make of it. The #1 goal is a safe round. The #2 goal is a consistent round. #3 is a crazy accurate safe load that can dot an eye at x range.
My .02 worth.
