I appreciate all the feed back. Getting a copy of the ABCs and Lyman's. Possibly more. There are two areas I'm really hoping to get educated: the WHYs of everything involved in reloading, and everything there is to know about powder (I need to find almost a chemists analysis of gunpowder. I see there are different brands and I assume they have different chemicals in different proportions and I'd love to understand why they are different). I don't really need all that much in the way of cartridge data. Right now I only have a .45ACP pistol (Taurus PT145 Millenium Pro), and I don't have any desire to get fancy with my loads, SAAMI specs will do just fine.
Looking forward to reading everything ever written on these topics. Can't wait to be a contributing member of this forum.
Your 9mm could, and in all likelihood will expand. But my .45 will never get any smaller.
