I think you need to watch the video again. I watched this a couple of weeks ago. If memory serves me correctly, the shots were good shots. It just didn't die yet.
1 shot went through the front shoulder and vitals.
1 shot was right behind the shoulder also through the vitals.
1 was high neck/spine but missed the spine.
If you listen to the video, towards the end you'd hear about their take aways from the hunt. Watch some of their videos, they shoot long range all the time. They did say they should've gotten within 300 yards and regretted shooting it uphill from them.
I think the biggest take away should be for us people who reload. Use your newest brass and make sure the primer pockets aren't loose if you're going to hunt something that might try to kill you. Everyone should carry a pistol, and certainly don't let a bear know where you are.
They yelled at the bear to try to get it to stand up. That was a bad idea. If the bear can figure out that you're there, they'll come for you if you wound them.
Watch the clip below. If the bear saw him pump his fist, the outcome would've likely been extremely different. It's almost the same in every brown bear video. Once shot, the bear looks around to see who did that. Best to stay still!
He was the one who shot it. But regardless, he had 2 solid hits, one neck shot that missed the spine, but these guys & gal definitely know how to shoot.
