I've had two odd shots with my 480Ruger this year. Neather had to do with it being a 480, but that is what I was using at the times they happened.
First instance was shooting a pop can against a dirt backstop. The jacketed 325 grain hollow point entered the popcan then hit the side of the can resting againts the dirt. It then ricocheted inside the can, but instead of exiting the can, it took the can with it. The can flew at a high rate of speed 20 yds or so away from us. When I picked up the can the bullet was still in it in nearly perfect shape.
The second instance was today. I was testing some 380gr cast lead handloads that I would estimate at 1200 fps. I stood up a piece of 2" thick styrofoam about 12" in front of a basswood stump out in my front yard. I stood back and fired five shots at about 25 yards. Made a nice 5 hole group just over two inches. Anyway when I picked up the styrofoam I discovered a bullet lodged sidways in the back of the styrofoam. It must have bounced off the frozen stump (it is well below zero out) and stuck back into the styrofoam. The other four bullets had penetrated into the stump. This bullet was in perfect shape except for the land & groove marks on it.
