I sometimes buy commercial cast bullets for blasting large volumes when time is short for casting. I have been trying some acme coated bullets lately for light 44 mag and special loads. Loaded to about 850 to 950 FPS ,I tend to get leading in my smith 624s and 629s. These are bevel base commercial 240 grain bullets. Even though bullet fit is far from perfect in these different guns, I am not too impressed with that coating. Anybody else had similar results. I think at that low velocity, leading should be minimal. I am sure I could coat with lla or 45/45/10 and eliminate but that defeats the purpose. Any other experience with hy tech coating and it’s lubricatiting properties?
