In all honesty the best value for loading and mucking about with forearms has been a 6" mitutoyo digital caliper.
Yes, that's a good one. It's one of those tools people take for granted and don't think much about, until you don't have one.
Along with the caliper, my best reloading investments were:
Dillon 550
Dillon digital scale
drill press (for case prep) and Lee trimmer pilots
ProChrono chronograph (boy was I pleased to upgrade from that Shooting Chrony!)
House with a yard where I can shoot
We could have a whole 'nother thread on bullet casting investments.
