All those bears are Awesome!
My taxidermist, Jim August, has a 10' 4" bear mounted like Salmonella's bear in his showroom and the size of it never fails to humble me. You can't understand the size of one of these monsters until you see one up close standing like that...
Personally, I'll take your collective word that the 300 WM will kill one, but after seeing one up close (mounted), I'm still thinking I'd feel undergunned with anything I could carry!
JBabcock, you are definitely on my list of people I am jealous of! LOL-- congrat on some truly fine bears.
