Which begs the question...
Why bother hunting, tracking, stopping wounded bears with anything over 30 caliber?
OR
Is there a scenario in which the over 30 cal rifle gives the hunter or guide an advantage?
I used a 300WM through the late '80s-early '90s and felt comfy enough with it. I stepped up to a 375 and then a 375AI because of a couple situations that left me wanting a bit more.
Coincidentally I started shooting Barnes bullets about then...
Any of my smaller bore rifles are lighter than my 375s... and they handle a little quicker.
