New Reloader??
Hey, first off, welcome to the club!!
You'll find a world of fun in reloading.
Before you buy any equipment, though, you should do some homework. Get and read
The ABC's of Reloading ; it is the most comprehensive introduction recently published. Published by Krause I believe. Then get at least 2 different loading manuals and study them. The Lyman manual is good, but, heck, so are all the others. Talk to reloaders at your local gun shop and rangeÑMost will be delighted to give their opinions and help.
Read the cautions; they are there for good reason. We are dealing with powerful chemicals, here, and pressures that can ruin equipment and maim or kill, if they get out of control. If you are one of those folks who cannot or will not follow directions, who must always be doing it "my way," who thinks they know more than the experts, who must always be pushing the envelope, who thinks that if a little is good, a lot more must be better, than do yourself and society a favor, and DO NOT FOOL WITH RELOADING.
If you are a mostly reasonable and prudent adult, you will experience no difficulty, and reloading will be a safe and enjoyable pursuit.
That having been said, again, welcome to the club. Almost all of what has already been said, I agree with, except that you should definitely start with a single-stage press. It's so much easier and less annoying to correct 3 finished rounds after discovering a problem, than to cheerfully run off 500 wrong ones, and only then discover an error, as you can with a Dillon or the like. And I understand that setting up a multiple stage press can be a real PITA, especially for a small run.
Enjoy the learning processÑit's part of the fun. And you're never done. There is always more to learn. You're always a student of reloading, never a master.
