300 grain Hornady SST with 48 grain IMR 4227 CCI 209 primer. Its topped with a Nikon 3-9x40 Prostaff and a Harris 9"-13" bipod. I have shot 4 deer over 200 yards with that load, and I have never had a bullet stay in a deer with that gun. I have shot 25 or so deer with that gun and not one ever took a step straight down.
