Next we'll be hearing of a successful bear defense using the BB .38special +P "Outdoorsman" load, I believe that's what it's called, with the hardcast bullet.
Two documented cases where the .38 Special was successfully used against grizzly bears.
Alaska, 1947.
October 1947 Chickaloon River, Kenai Peninsula, Alaska, grizzly bear .38 revolver, 158 gr bullet. Page 95-105, “Narrow Escapes”, Ben East, first published by Outdoor Life, 1960.
