Jay,
Do you believe that you are going to "stop" a charging bear with the 3000 Ft Lbs of the Brenneke slugs? I don't dispute that the rifled slug is the best weapon at short range for a grizzly in many ways. I might have carried one, had I figured out a way which was as non obstructive as the .44 mag (which is only about 1/3 the energy). I had given it considerable thought before making my decision. Again, different strokes for different folks--and I think that having to shoot a bear is both going to be very rare, and traumatic for all!...Thus the spray; try and trained myself to spray/and shoot... (with fairly low energy .44 specials).
But the mass of that animal is still moving, and the teeth are still capable as are the claws until that animal is really dead...
Don't know if you are familiar with the US forestry study--old, and flawed in many ways, by modern standards, but still interesting, if nothing from a historical value:
https://www.fs.fed.us/pnw/pubs/gtr152.pdf Key is that the .375 H & H magnum came in 3rd after a .458 Winchester Mag and the almost un-shootable Weatherby .460 Mag. (over 6000 ft lbs). The 24" .375 with a 300 gr bullet gave almost 5000 ft lbs the 20" (which is what I believe the Forrest service still uses today) comes in at about 3800. But that was no where near the entire story. The 12 gauge (and it is considerably less than the Brenneke round) came in way down the line...
Relatively recent shooting in the Sitka area:
https://www.adn.com/alaska-news/wil...-workers-kill-charging-brown-bear-near-sitka/ Several lessons there--one worker had the spray, the other rifle--decided that the rifle was the solution...Probably the correct call...but who knows.
Unless you have a heart/aorta/carotid artery shot or a brain/spinal cord shot, (and as we both know that is going to be very difficult) that animal is still going to keep coming.
Yep, I know that the .44 mag is a very distant down the line choice (But they scored it just above the 12 gauge)--despite at the time, having the best "results"...(I made the decision for .44 mag in 1991--and at that time basically the .454 Casull and the .500 S & W were not available. Not sure I would have chosen them if they were....)
I wonder how many shots the bird hunters in the article by Andy would have needed with a slug, rather than the bird shot? I was not aware of the Brenneke slugs--thanks for that info. I don't have any worry here--in Florida--we do have quite a few black bears--one not too far from my home last fall. But they are small, and generally very spooked by man. There were some attacks however in the last few years--most recent one in January. I usually carry when out and about--and if on the trail--.357 mag--probably enough for the bears around here--again, if..I don't carry my large pepper spray, but have one which has about a 15 foot range, which I often carry.
Sure wish I could get back to AK--but not going to happen--heck I am lucky to still be alive!
Take care-
