Time to React:
In 2019 we were perched on our hillside a short distance above base camp, glassing for game. A sow grizzly with two young cubs showed travelling down the river bed about 150 yds distant. None knew where we were. I told my partner to shoot his AR15 into the ground to the side of the sow. Don't like grizzlies around camp. Especially sows with yearling cubs.
First shot, the sow looks around wondering what was up, but not too concerned. She doesn't really start heading out at all. Shows just a little concern. Tell my buddy to shoot another round.
Second shot she's immediately on alert. Looking all around her first and next turns to locate her cubs, which were trailing behind some 40yds in sparse brush. I don't know how she communicated to her cubs, but they came to her at a fast walk. Now the sow moves forward 60yds and the stops for awhile. Not as relaxed as when she first showed. Tell my buddy to shoot again.
Third bullet slaps into riverbed gravel and rock about 6yds to the side, and upwind of the sow, at the base of some willows. Kicked up some visible smoke/dust. Sow stands erect on rear legs, jerking neck in all directions, clearly alarmed. When the smoke dust drifted to her, she attacks the location of the bullet strike. Three quick pogo stick hops on rear legs has here into the clump of willows. Her front paws are just a blur, parting the willow branches, while she's looking down for the threat. Then unable to find anything to kill, she hesitates, drops to all fours, and heads for the hills at a gallop.
Whole point of this story? If a guy had been in that clump of willows, it woulda been curtains. This sow was out for blood. The only way a guy woulda had any chance was if the firearm was in hand and pointed toward the sow at the moment she started her attack. It was both alarming and frightening. I looked at my buddy and said "we just witnessed what mauling victims see, just before death".
It was a sobering moment. Something I'll never forget. Still can cause the hair on the back of my neck to stand on end. Spookier than when a black bear stalked me by scent, sneaking to within 20 feet before I could respond and kill it.
Just thought I'd share this experience for others consideration, when deciding on what firearm to carry, and how & where to carry it.
That sow woulda killed the majority of us, if not all, no matter the weapon carried. She came unglued and moved way too fast to respond.
