Predator Turnabout

"He was well-armed enough. He carried his MegaBeast, a short-barreled custom rifle tricked out by Gary Reeder in .610 GNR, and he wore a BMF revolver in a hip-holster, the sidearm chambered in full-power .500 Max, loaded with five 510
GNR cartridges, either of which gun could drop a twelve-hundred-pound brown bear dead in his tracks with one shot, should the need arise."pg.16 chpt.1
