I do quite a bit of reloading and it depends on what your looking to do to be honest. I have a friend that is a custom reloader as a living so I can give advice from that standpoint as well. 1. To manufacture and sell ammo, you need a license from the ATF which I believe is only $25-$50 per year. You can find it on their site pretty easily. 2. Before you can even think about a return on investment of your equipment, there are multiple things to consider. You will be able to pay for your equipment fairly quickly if you are loading for yourself and shooting quite a bit. How quick depends on what you are loading. .308 and up will give you a ROI quicker then pistol will. If you are thinking about making money reloading and selling, you have to find a market. 5.56 and pistol for people you know will be quickest assuming they want better then bulk and cheaper then factory. (fyi, your reloads probably wont be better then factory but may be cheaper if you dont count your time. . Youre only possibility of an sales audience is the random range go'ers, AKA, people just dumping rounds and dont really care about accuracy. 3. Accuracy in reloading takes a shitload of time and to make it go quick you need some fairly expensive equipment. 4. With that being said. I think after you look at the time and equipment it takes to reload for yourself, you will no longer want to try and reload to make money. And lets not forget the liability issue which I wont even go into. My suggestion would be to start loading for yourself and you will find out real quick if its something you want to do. Being honest with you, I would never buy reloaded ammo from someone that just got into it because you dont have the experience and havent had those "Oh shit" moments that really cause you to learn and be meticulous. You need to load for yourself for a good long time before trying to load for someone else.
