I'm thinking of getting into reloading and have some questions about it. First off is it difficult to reload and do it safely? Don't modern reloading presses have a digital scale that tells you exactly how much power your putting into a case?,This way one can't overcharge a round which could be dangerous obviously. Also the calibers I want to start out with in reloading is .38special and .357 magnum and maybe 9mm down the road.
As I understand it I have to buy the dyes for the caliber I want to reload for,but what exactly are they? As you can tell I know nothing about reloading so any help would be great thanks.
