I've had this gun done for a few weeks and just got done load testing today. Lawton 8500 action, Brux 34" barrel, Muscle Brake (works awesome!!) Mcmillan A-5 Super Mag, Leupold 8.5-25 scope. 134g H50BMG throws the 300g SMK at 3196 fps with no signs of pressure. 300 yard testing showed 3/4" 4 shot groups. Everything but the scope was Duracoated matte black, (I know it's very plain looking, but it's meant to be a killer not as much a show piece) Hope you enjoy.
