In my estimation the limited reaction time during an all-out charge is overrated. This is my experience only and is based on just one full-on bear charge. Approx 200 pound black bear uphill. My first shot was approx 50-60 yards, then with a full-on unimpeded charge directly toward me there was sufficient time to run my bolt-action 30/06 and an unhurried shot to end the charge at approx 10-15 yards. I know there are many scary accounts on an internet search but my one encounter was much different. Would like to see others' real experiences not tainted by internet stories.
