Best advice I ever got was to read at least 2 manuals carefully (the instruction part, not the load listings, of course!) before touching your press. That helps a lot, and don't stop there! I keep 5 manuals plus manufacturer sites and internet sources...
I agree, you're going to want that factory crimp die in the 4-die set! I get one for every set that doesn't have it. You can always crimp lighter rather than heavy, but you can't beat that consistent diameter of your loaded rounds.
You're going to love that 0430 loading! Quiet house = good loading. Don't load distracted, it's not worth the risk.
Or drinking, never load when you're drinking, lol.
