The Ruger I received on my 16th birthday now has an Intrafuse stock and a couple other things installed (grenade launcher, flamethrower). Here in the desert, the primary yard pest is the gopher. One day I popped some Aguila subs into it, and sighted in on a particularly annoying, grinning varmint about 40 feet off the front porch. Every time I squeezed, he ducked by the time the round got to him. I swear he was zoned in on my finger. Not only that, he ascertained that I was using a short mag, and when the 10th round went for naught, he jumped out of the burrow, picked up two bullets out of the dirt, sighted on me, checked the air for cross currents, and flung them back.
You can imagine I was not prepared for a firefight with a damn prairie dog. I could not defend. I spent two weeks in the hospital with life-threatening injuries to my neck and chest. While I did pull through, I had to endure the embarrassment from the hospital staff snickering every time they came into my room.
True story, I swear. Lots safer shooting at paper targets. Lesson learned.
