Avg bear killed here in MN is about 140lbs and our DNR notes live trapping 800lb bears and not like it's a once in a hundred years thing, there was just one that would have been over that killed illegally a year or so ago as well.
But that tends to be reality vs fantasy a lot of the time, you can sure always hold out for big regarding anything, big money gains, big bull elk, big boobed 20yr old blond that likes crazy old fat guys...
Eventually you may want to just appreciate reality though, maybe.
Oh and I just built a 458 lott and I run a 500 S&W on my chest, call me a worrier or not, I plan do die throwing a lot of noise and power at whatever kills me.
I think I keep noting I hope to do this exact hunt some day, had 3 different bears within 20 yards of me dozens of times last year right out in my backyard but it takes us 3 or 4 years to draw here. Idaho or Montana for a spring hunt sounds like a nice dream.
