If you don't shoot that much, reloading is not for you if you are doing it to save money. I can buy 45ACP Federal American Eagle for about $13 a box of 50. It probably costs me $10 to reload them, using the same brass.
I reload for a couple of reasons. 1. Its a great pass time. 2. I can tailor my loads to a particular rilfe/handgun. 3. Satisfaction of taking game or shooting tight groups with my own ammo. 4. Cost, simply because I shoot a lot. At least once a week with different weapons. But the cost savings is the least of my concern. Don't forget, if your starting out there is a lot of equipment you will need to purchase. Things like press, scale, dies, powder dispenser, case trimmer, primers, powder, bullets, brass, etc., etc. This will add up to a few hundred $.
