I have actually been charged by a grizzly and killed it.I was grizzly hunting when the bear appeared about 100 yards off as we climbed a slide to get to a good vantage point.It stood on it's hind legs and tried to smell us before returning to all fours.Then it began walking towards us on a sheep trail.I was deciding if this bear was big enough to kill,when the bear began to trot,then changed to a flat out charge towards us.At 40 yards,I fired and the bullet struck the base of the neck.The bear stopped in it's tracks and turned,so I broke both front shoulders with a second shot.It rolled a couple of hundred yards into a pile of brush.We rolled it down to the river bank and skinned it,finding the first bullet in the rear hip.I was using a 338x8mm remmag with a Jensen j26 bullet.The bear weighed around 400lbs and squared 6'8".
