I think he was using his 7mm Rem mag. with 175gr. noslers, but I'm not 100% sure.
They drive hunt a lot for 'em around here, the bears just hold up in the thickest stuff you've ever seen after opening day.
My buddy & his group usually send the walkers through big gullies that are thick with tornado slashings. They put the shooters up on the ridges to watch down in & a couple guys @ the end of the ravine & push 'em out.
This is just hear-say though, like I said, I haven't gone after 'em (yet)
