It was an interesting video. What I found a bit conflicting was bear spray @ 4 second full discharge at 20-30 ft and if it doesn't stop the attack, drawn (or have at-ready) the sidearm to continue the fight, which the author accomplished in training mode, 7 rounds in 6 seconds on target.
Let’s suppose 20 feet, 4 sec. blast of bear spray, followed up with 6 seconds of gun fire…and likely charging bear speed will cover probably that 20 ft. in - 1 second...and that’s if a bear is applying the Tueller Rule. Time is a luxury.
It’s going to take a good amount of practice… or narrow the choice of the two options?
I don’t know but I think if a bear is already in charge mode at 20-30 ft, it’s a darn good to convince me it isn’t just going to stop on the dime. I wouldn’t want to be in a predicament to guess wind direction and when seconds count, trying to fog it’s snout before it takes a swipe at me.
I don’t spend any time in the backwoods of any bear country but the kids do and have expressed interest in the .44 though never shot one. The only advice I could render is to find so with a .44, then try out (my) .38 spl, .38 +P, then a .357 magnum load for a feel. Then try getting 6 rounds on a 12” bullseye as fast as possible with each of the three loads. Finally while still fresh, try 6 with the .44 magnum.
I forwarded them the article, hopefully it will shed an informative light on situational awareness and training, but also I‘ll bet the 10mm will be the choice.
