Bigbore5 is correct.
Casting your own bullets isn't hard. Remember, our Country founders did it all the time & won the American Revolution using home cast balls.
The initial expense isn't very prohibited when compared to the retail pricing of bullets.
You can buy Lee stuff including molds and be set up easily. I recently couldn't pass up a deal I'd found on a set-up. It was a Lee 20 lb pot, a PID Controller, (that controls the temperature of the lead constantly,) a quality hotplate, and 50 lbs of muffin ingots of lead for the sum of $150.00. Add a mold,, and I can begin casting with it. Lee molds aren't expensive & a good place to start. I prefer the MP brass molds,, with their nose options, but they do cost more than Lee molds.
Powder coating is easy, not expensive, & WELL worth it. Add a sizing die,, and you are in business. About 90% of my shooting nowadays is done with my own cast bullets.
Just yesterday,, I have a young man, a neighbor who stopped by to get 100 of my cast bullets for his .357 Maxi. He loves them. He's not gotten into casting yet,, as he's just been reloading for a bit over a year now. But he wants to learn. I plan on teaching him.
