A .22 worked this time....
Back around 2002-2003, there was a wild dog roaming about in the woods on the road where I lived. A group of 5 houses were all on the same side of the street, with woods behind our homes as well as on the other side of the road. Several neighbors and my wife had been telling me that when they're outside, this dog just isn't acting right. Very hostile and aggressive. In one case, this wild dog actually mangled a neighbor's dog. Mauled the dog but good!
As fate would have it, I'm now cutting our grass when I saw the dog that they'd been telling me about. He was in the yard next to ours and he was just giving me the eyes. I went inside and, for some unknown reason that I still can't understand, of all the guns I have, from AK's, M4, assorted shotguns, many .45ACP, .40 and 9mm semis, I for some crazy reason grabbed a bolt action single shot Glenfield Model 10 that I had not shot in at least 2 years. I loaded it with a single .22 from an OLD box that I had. Instead of getting some of my fresher ammo, I just dug for the oldes box. Had one extra round in my hand. And then I went outside.
The dog was right where I last saw him. I started walking towards him in the big open yard that ajoins both properties. After I took maybe 10 steps, the dog flat out charged and I mean to tell you, he looked mad, ears pinned back, and was coming really fast. I dropped down to one knee and was waiting to see how close he could get before I would fire. At that exact moment, the thought came to me....what if the gun doesn't fire? Or what if that ancient .22 doesn't go bang? (I promise, I'm not making any of this up, especially this part.....I started giggling!) I KNEW I had one shot to get the dog or he would be feasting. He was coming full bore, straight at me and I fired at his upper chest-neck area. The gun fired and the dog fell forward and didn't roll at all, he just skidded. The second .22 finished it off.
Nothing like that has ever happened since. But if a similar need arises, like Springfield Armory says, I'll "bring enough gun!"
