I have a Lyman, Hornady, Nosler & Sierra loading guides. Have read all several times. As I bought each piece of equipment I learned how to use them before moving to the next piece of equipment. I wrote out a procedure about what I needed to do (steps) to reload a round for one of my rifles. This took a couple of weeks before I attempted to reload a round. Check & double check. I've been doing it for over 10 years and still learning. It's not a race. Take your time. I was at the range one day and they were loading a guy in the ambulance. He was shooting hot loads and his gun practically blew up on him. I heard it messed up his hand pretty bad. Be safe!!!
