memtb,
Most outfitters aren't gun guys like us. I believe Ed Nixon was a gun guy, he often mentioned his 338 and the faith he had in it. Working and living in griz country he was a wise man to choose the 338.
His writings influenced me enough when I moved to griz country I built a custom Mauser 338 of my own.
I have hunted the Swan & Bob Marshal and yes both are full of grizzly bears.
