Title explained the goal but not the whole situation. So my uncle has black bears openly tearing open garbage bags and dragging them all over the property in broad day light right before his eyes as if to add insult to injury. Now he is not within the Pisgah Bear Sanctuary like my house is so really he could dispatch them during hunting season but he's too soft for that. He hit me up this morning knowing that I reload for 12 gauge and .410 wanting some less than lethal 12 gauge 2 3/4 inch loads to scare the bears away. I have never done less than lethal and most of the stuff I've read elsewhere sounds inadequate, for example I red 6 grns of red dot with an empty wad over a fed209A. 1 I'm afraid that will squib and end up with a plastic wad stuck in the muzzle of my uncles modified choke gun and 2 I doubt this would run off a trash fed spoiled rotten bear. This data came from a guy that was running off stray dogs. I've heard tail of using dry beans like buck shot but I wonder with how much powder? I'm guessing something like 15 grns green dot with. 12SO in a cheddite with cheddite primer and as many dry beans as I can fit
I have that bears first cousin living hereabouts..............been going on for a couple of years and as the gracious state of Florida forbids lethally addressing the issue I picked up one of Fith Op's .12 perimeter alarms...........installed a latch on my 90 gal container that he broke the lid on.......re-installed said lid with the alarm jammed under a handle....he tips the can, device goes off.......bear leaves post haste. I understand he's laying waste to the fancy subdivision to my south where a couple of years back some NY or NJ type tried to 9mm one.....finally died and FWC had a field day writing citations.
Not a permanent solution, but neither are your less than lethal loads...........my perimeter load is a cut off federal stoked with 90 grains of triple f, topped by two 23/8 hard card wads, roll crimped............loud, flashy, stinkey..........and works...............thought about using some of the flash bangs or specialty loads but so far not necessary.
