I am going to begin reloading .308 winchester for my steyr scout, primarily used for stalking. I have read Richard Lees second edition reloading manual. I have read through some of the load data for .308 winchester. I am going to start with 150 grain jacketed bullet. I have some geco,remington,winchester brass to try. I am a little confused as to which powder is more suitable.I was also toying with the idea of trying a 120 grain bullet as well. What benefits are there of me using a smaller grain bullet? Can anyone advise me further as to what would be suitable and why. Many thanks, Ed.
