I would like to start reloading. Specifically the 45acp for target and the 357 mag for hunting. I would like your thoughts on a good starter dies, press, primers, gunpowders, etc. Does handgun brass stretch enough to warrant a trimmer??? Is there a guide that is better than others?? Sorry for all the questions, but I want to make sure I don't blow my hand off. What are good indications that you cannot use the brass anymore.
