I'm just getting started at reloading, and I'm shopping around for things I need. I see that there are steel dies and carbide dies. What's the difference and is there a preference of the two. I just really wanna buy them once. I'm gunna be loading 9mm and .223 rounds. I have a RCBS rock chuckler master kit. Do any name brands work with it? Thanks for any advice. And I see on the dies they say full length and small dies what's the difference in that too? Thanks again.
