We have a widow friend who has a black bear on her property and doing damage. This fall, when it is legal, I wil go after it with my traditional muzzle loading Jaeger flintlock rifle in .54 caliber. I will be using a pure soft lead cast roundball with proper patching and 100 grains of 3Fg real black powder.
If using my suppository gun it would be the 30-06 using a hand loaded 150 grain Nosler Ballistic Tip.
BTW, she also has a destructive mountain lion on her property. Officially they do not exist in Arkansas but I will try to get a predatory permit to kill that one just to stay out of legal trouble. Would use same fodder as for the black bear.
BTW#2: I will be trying to call them with calls I make.
