You did right by setting it up yourself. You need to know how to make corrections so might as well know how those dies work. I do think it is a good idea to have someone teach you at the start so that you don't have to learn from your own mistakes, some of which are dangerous. I had three squib loads after I started reloading with my RL550B and had it not been for an excellent instructor I would have tapped & racked only to fire on a obstructed barrel. The next two I caught thanks to the first. Best thing I did for this was to buy one of those reading lights from a dollar store which allowed me to shine light through the center hole in the tool head and see powder in the case before inserting the bullet for seating. Now I know if I have powder or if I have a double charge which is also very dangerous. Other than that it just a matter of getting a precise round. Once you have that it's all downhill and that's when the fun starts. I love spending time in my reloading room and producing a good round. You will be happy with your Dillon, that's for sure!
