Note: "Brenneke Black Magic" come in both 3" Magnum and 2.75" Short Magnum varieties.
If you don't want the mule kick of the 3", you have options.
reading oldmanFCSA's story though...man I'd step up and get their 3" Magnum Crush load. I'm sure it kicks like 3 mules but I'm pretty sure I'd about **** my pants if a bear came at me full tilt, 10:30 at night or otherwise.

In all fairness, I won't feel like my home is defended until I own an RPG, and then I'll start having bad dreams about robbers in tanks. So maybe I'm just overly cautious.
