Last September, I was looking for 9mm 115g bullets, and there were none to be had. Someone here at CFF sent me a link to RMR's website where they had them, but instead of COPPER FMJ, they were BRASS coated. They were in stock, so I bought 500 to try them. I was reassured that I could use the exact same load I used for copper FMJ bullets. I loaded about 5, and test fired them in our back yard just to see how they cycled. All looked good, so I loaded 100 rounds- and never made it to the range- until last Friday. I'm happy to report that they worked perfectly. My wife shot half of them in her new Springfield Armory Hellcat, and I fired the rest in my Glock 26. We saw no difference between these loads and my other 9mm loads, or commercial ammo. In fact, I actually shot my G26 better than anything else I've run through it before. I was happy! I just ordered 1,000 more (brass plated) from RMR. They actually still had them in stock!
