My advice? Read various books, and don't get in a hurry.
Search the archives here and browse.
Any time you're at a gunshow and run across a good used reloading book, if the price is right, buy it.
Don't ever get in a hurry.
Then, when you actually start reloading, write down all loads, and date them. If you try test-loads, 3 to 5 loads with a bit different powder as you work up a load, use a magic marker for color coding (just a swipe across the case-head) and write it down!
Double check yourself from time to time as you go. When you use a powder measure, go to the scale every 100-200 rounds and make sure it's still "on weight".
And don't be in a hurry.
