Harold Johnson necked out the .348 Winchester case to accept a .510" diameter bullet, and Harold Fuller developed the barrel, marrying a .50 caliber barrel to an old Winchester Model 1886 rifle. Since the rifle was designed for use on Alaska’s great bears, Johnson cut boat-tail .50 BMG bullets in half, seating the rear half upside down in the fireformed .50-caliber case. It didn’t take Johnson long to find out that the 450-grain truncated shaped “solid” would shoot through a big brown bear from any direction, claiming in 1988, “I never recovered a slug from a bear or moose, no matter what angle the animal was shot at.”[citation needed]
