Been reloading 40+ years. Over the past 25-years, I would purchase BULK everything for reloading when available at a good price. I now find myself with enough supplies that I should have all the ammo I need for the rest of my life.
Purchased my first 380 in March 2019 and had plans to buy ammo. With the Chinese Virus causing ammo supplies to dry up, I was able to find 380 projectiles from my favorite mail order supplier and received a shipment of 4,500. I saved most of the brass from the 1,000 round reliability and function testing on the 380. I had primers and power so only dies and conversion kit were needed to start loading my own. Have now produced 300 or 400 rounds at a cost of 12-cents each for consumables.
When I lived in SoCAL (Los Angeles County), indoor ranges did not care if I brought my own ammo as long as it was not a lead bullet. Copper jacket or copper plated bullets were ok. They did not want the extra pollution in the indoor air with the lead bullets. Typically I shoot moly or hybrid coated handgun bullets at outdoor ranges and they are my preferred projectiles for practice with handguns or PCC.
