Marketing and perception (maybe the same thing) are going to be among the most vital aspects of your potential new business. Here's a quick story to illustrate... In Western Florida, we had a guy doing "professional" reloads on a fairly grand level. He provided all the practice ammo for the local cop shops and cop ranges, so he did a huge amount of 9mm, .40 S&W and .223 ammo. He did .38 Spec., and .357, too as well as .44 Mag and various other calibers. His prices were reasonable and between the police and regular civilian shooters who bought his product, he sold about as much as he could produce. Until one of his .223 loads blew the bottom out of somebody's AR.
Now, maybe it wasn't the fault of the load. Maybe the AR was faulty. Either way, our local guy denied any responsibility and ignored requests for an impartial examination of the weapon a nd the remaining ammo.
When this word spread around, cop shops cancelled their contracts. Local gun shops refused to sell his re-mans. Most shooters (myself included) refused to buy/use his ammo because even if it wasn't his fault or the fault of his ammo, the fact that he didn't step up gave us cause for pause. And we just didn't trust him. He has now started a "gun smith" aspect to his business because re-manufacture was suddenly rather less profitable.
Almost immediately, another re-manufacturer stepped into the void. Company called Hyperion set up shop in our county after moving in from a neighboring county. I'm not terribly happy with them because it's almost impossible to get any sort of a response from them to questions I might have. And special orders are not high on their agenda. For example, if I want a heavier bullet for my FMJ 9mm practice rounds so they approximate the hollow point rounds I carry every day, I'm out of luck. So, I now purchase on line or at one of the gun shops I frequent.
Since the start of the current Administration in Washington D.C., ammo has been increasingly easier to get. More companies are making and shipping new stuff and the prices have been dropping. All those jerks who bought and hoarded .22 LR and were selling it at onerous prices are crying in their beer since I can buy it from WalMart for 3-cents a round and sometimes less. 9mm prices are dropping. .223 prices are dropping. Even hunting rounds are coming down in price due to over-supply and reduced demand since no one fears the Feds are going to shut down production.
So, Tab, I would sound a couple of cautionary notes: 1. When new ammo has yet to find its actual bottom price, re-manufactured might not provide enough margin to be viable; and 2. When it's unlikely that government regulation will be reduced from what we have under Trump, and the only real possibility is heavier regulation under a future Dummycrap Administration, is it wise to bet on the re-manufacturing business?
Tab, I don't know if you can afford the fairly hefty start-up costs and then write them off as a "hobby," but unless you have a great stash of dough to risk, I'd maybe give this some additional thought.
FWIW
