I've been using Precision Delta 148HBWC-ML for awhile. Excellent bullets. I'd suggest their match lube ML, which is a dry lube.

I clean my dies after every use with Hoppes, then I wipe them down with Starrett M-1 oil. The M-1 oil leaves a unique protective film. It's the only thing I use to clean my dies, calipers, micrometers and tools. I'd never rely on WD-40 for corrosion protection.
I keep my loading records in a spreadsheet. I use an Apple computer and the Apple Numbers spreadsheet, but frequently wish I had a database. I maintain my brass in Case Lots and keep records of each loading.
