One lucky shot

From Wyoming:

It was a one-in-a-million shot, but luckily for Ron J. Leming, his father accurately fired the arrow from his bow the one time it counted the most - as a 500-pound grizzly bear chased him downhill.

Ron J. and his father, Ron G. Leming, were archery hunting for elk up the South Fork of the Shoshone River in northwest Wyoming in mid-September, about 15 miles into the Washakie Wilderness from the trailhead. It's an area they are familiar with, having hunted there for the past 15 years.

For three days they'd bugled, cow-called and worked the woods, hoping to shoot a big bull. Fall is when elk breed. Big bulls bugle to challenge other bulls in hopes of breeding more cow elk. Hunters imitate the sounds in hopes of luring the testosterone-amped bulls into range.
...
The grizzly staggered down the hill about 80 yards and fell over dead. With his first shot at the running bear, the elder Leming had likely nicked the bear's aorta, causing it to quickly bleed out.

"I was covered in blood," Leming said. "I didn't know if it was my blood or the bear's.

"My dad pretty much saved my life there," he said. "That's the thing I cannot believe in this whole story. He stood there with a bow and made that shot at a charging grizzly bear. That's amazing. You could take that shot a thousand more times and never do it."
...
Although the Lemings both had bear spray and pistols in camp, they had packed neither along on their morning hunt. [emphasis added]
