First I cast 20 bool it's from the lee 160 gr. 312 mould I then gc'ed them and sized them to .309 I the did one coat of hf black powder coat dry tumbled cooked them in toaster oven on toast for 15 min I them recoated and renamed for another 15. I then resized again to .309 I will be loading them on top of 18 grains of lil gun and shooting them out of 16" 300 AAC ar-15. I will post chrono results and any issues next week.
