Standard dies, vs. Bench Rest, vs. Bench Rest National Match, vs. Precision with Micrometers. And then there is Small Base. If I'm just starting out, do I need anything but the standards? I'm guessing standards for me is fine......but who uses these others and why? (Small base......if those are to make cases smaller to enable them to feed better in semi-auto, pumps, lever action, etc......I think I understand that one).
