I was loading Rainier 125gr plated flat points with 15.5 grains of 2400 and sending them out of my 24" bbl Marlin 1894 Cowboy .357 @ 2000 fps before I read anything about limiting the velocity!
They were the cleanest, easiest loading and feeding, and not to mention accurate bullet for 50/100 yard target shooting. I shot up the rest of the lot without any problems, only nice neat holes in the black. They worked great in my Vaquero too. I just haven't seen any problem with that particular plated bullet....
