It depends on how much you want to shoot. In the long run, it's far cheaper to reload.
If you're going to shoot tailor mades, it will be expensive. Even surplus is starting to run 65 cents a round and that's for 60 year old corrosive stuff. Then of course the brass must be disposed of.
If you're really strapped for cash or really a tightwad, shooting really isn't a good hobby to get into. Every time you pull the trigger, it will cost you at least 50 cents with a centerfire round. With tailor made, new manufacture, a minimum of a dollar a round. Usually more. Then there is the cost of the range and getting there.
