I will be picking up a P380 and a PM9 for wife and me in a few days. I have been reloading 9mm with a moly coated Billy bullet and 45 caliber in a Bear Creek moly coated bullet. I have used these bullets for years with good success. I researched and get conflicting opinions on coated bullets in a polygonal barrel. I would be shooting 50-100 bullets per gun each week. I also have access to Frontier CMJ bullets which is a complete metal jacket. These sources are at the range where I shoot. I use W231 for the 9mm and will use it for the .380, too. Any thoughts or suggestions would be appreciated. This is a great forum to learn about the P380. Thanks!
