I recently swapped a Savage .308 for a new Ruger Hawkeye .308 and have been trying to perfect a good cast bullet load. Here is a report on my progress. I am using Lee molds that drop bullets of 157, 175, and 196 grains when using a 50/50 mix of linotype and plumbers lead. Gas checks of course are installed via the wonderful Lee sizer and bullets are sized to .309. They are just tumble lubed in Alox (before and after sizing). I am using SR4759 exclusively for the moment. Yesterday morning, with no wind and at 60 degrees, I was able to shoot 100 yard groups of .5 inches (3 shots) using 24.5 grains SR4759 under the 157 grain bullets. I got a .6 inch group with 25 grains of SR4759 with the 175 grain bullet. The best I could get with the 196 grain bullet was 1.5 inches with 22.5 and 24.5 grains of SR4759. Still a work in progress, but I think I will concentrate on the lighter bullets. All bullets were plus or minus a half grain and all powder charges were weighed. I was using WLR primers and Federal brass full length resized. All bullets were seated to the same depth, to the bottom edge of the top grease groove, resulting in three different cartridge lengths but about the same jump to the lands for each. That's an area I will need to work on. In any event, after 40 shots, I had no leading, and the barrel was shiny clean after a few passes with bore snake. Didn't take my chrono to the range, but from past experience, I think all of my loads were in the 1900 to 2000 fps range. Cast bullet loads are easy on the shoulder and easy on the barrel. If I can get consistent accuracy like this, who needs jacketed bullets?
