Velocity variation doesn't matter nearly as much as most people think either. Below 10fps SD you'll see next to no improvement. The difference between 15fps and 3fps is about a 3% increase in hit probability at 700yd.
Improving your wind reading, choosing a good cartridge, and using a good rangefinder have a significantly bigger impact than anything you can do at the bench. Two of those you can throw money at, one takes a lot of practice and rounds down range. The vast majority of shooters would be better off with a load they can put togeter quickly and inexpensively, and spending their time and money at the range rather than the bench.
