There are many good pros and cons pointed out here. For me it IS strictly a cost thing, typically about %50 less. But as others have said it depends on volume. I, on average, have 10k rounds of various stuff on hand at any given time. Don't pick up a gun without firing one or two boxes in a session. Don't waste my time even setting up the reloading press unless I have more than 500 rd to do. I agree that some rounds, like 223 are not worth it (used to do them and found I wasn't saving money over new). Some will say you 'need' the best (read most expensive) press out there. That may solve a few headaches in reloading but you must understand that you may have to do thousands of more rounds to break even. Other points to consider; buying reloading components in volume also cuts the cost but these days, shipping costs being what they are, lead is about the most expensive thing to ship. Politically speaking, reloading may be your only option in the future. One final point; courts being what they are I would NEVER reload self defense ammo. Others may disagree but just my two cents.
