I started reloading about 6 months ago. I don't know a whole lot, but I've had great success so far with my pistol ammo- .38, .45 acp, and 9mm. I got a Lee turret press with a turret for each caliber. I got the Lee 4 pc carbide die set for each caliber too. Once it's set, it's just a question of the powder charge, the bullet, etc., but I can switch from caliber to caliber easily.
I could make a lot more bullets with a progressive press, but I like looking at each casing, looking down in the casing at the powder charge, and looking at each finished bullet. I can then have confidence in my ammo and I have had very few problems.
I used the information with the press and the dies to get set up. I looked at several powders and saw several blogs. I was able to find Hogdgon powders locally to try them, so I went to their website, and they have loads for every combination of materials you can come up with.
I haven't sat down with a good loading book yet, but I did research everything available as I mentioned above and I'm off to a great start with reloading. Now when I pick up some books I'll know a lot more about what I'm reading, and in the meantime, I've got plenty of ammo at a decent price.
