My former side hustle. $800-$1,500 a week.


I used this to start my company. it's strange and most people will have never thought of it, but I was making a killing doing it. What you need: Access to a public, or private, shooting range. $10 coil hotplate from Walmart $1 stainless steel measuring cups from the dollar store Pair of pliars A muffin tin Metal soup spoon. A couple of 5 gallon buckets Fire extinguisher (recommended) Leather glovesSteps: basically money at shooting ranges is literally laying on the ground. So when you find a range you can legally access plan accordingly. Check the hours they are open and only go there when they are closed for shooting. Like the one I used didn't open until 1 pm on Sundays so I would get there at dawn and do a major collection.When you go to the range look around and pick up any brass bullet casings laying around. Those are money. Also go down the range when people set up targets for the second part, this one is a little weird. Pick up the fired projectiles. Get as many as you can. Don't go digging around for them, you can move around lose dirt by dont damage the range. Once you have a couple of buckets full, then go home and prepare.Ok these next steps you need to be in open air. Garage with the door open and metal table set up near it. If not table do it on the concrete. Or a car port. Somewhere with fresh air. Do not do this in a basement or a kitchen stove!!!You only need to do this step once. Take your hotplate and open the bottom. You will see 2 wires connected to the temperature controls. Disconnect those and connect them together. The plate gets hot and stays hot that way. To turn it on or off just plug it in or unplug it.Now unless you have a high temp smelter there is nothing you can do with the brass cases, so out them aside. Okay place the 1 cup measuring cup on the hotplate and let it heat up. Add some of the projectiles. As it heats up the lead will melt out of the copper because it has less if a melting point than copper.As the lead melts out of the copper use the pliars, while wearing the gloves, to remove the now lead free copper. Set the copper aside because you would need a smelter to do anything more with it. And just keep adding more projectiles and removing the copper until you have about 3/4 cup.Then use your spoon to clean the dirt off the top of the melted lead. Stir it some and do it again until it looks clean. Put the dirt from it into a small metal bucket or plastic bucket with water in it.Take the melted lead and pour it into the muffin pan and let it cool. Repeat these steps as many times as needed until you are done with all the fired projectiles you collected.Then just take all of that to any scrap yard. I was getting 50 cents a pound for the brass casings. 30 cents a pound for the lead and 70 cents a pound for the copper. Sometimes that will be more, other times less. Depends on the price that day.That's it. Do that 4 times a week or more and it's an easy way to make some cash with not a lot of work.Also keep in mind that the lead is a bullet grade lead which is special mixture. Meaning it can be sold but it is a specialty market and unless you know someone it can be hard to sell for that purpose.Any spacific questions feel free to ask. see hubwealthy.com/wealthy
