There is a video somewhere on YouTube of an air rifle shooting through a cast iron pot. I forget exactly what brand it was, but I found it when I was wanting a new toy that was quiet and cheap to shoot. Air rifles have come a long way.
I have a Winchester model 1000 single-pump air rifle, .177 caliber. I was sighting it in with a scope in my house because the distance from the back of my bedroom wall, down the hallway to the linen closet door was the same distance as my bird feeder was from my front door.
Now....I have a neighborhood full of squirrels that take great pleasure in dumping all the food out of my bird feeder....well, I USED to have a neighborhood full of squirrels :wink:............
Well, knowing the advertised velocity of this rifle (1,200 f.p.s.).....I decided to back my target with first a 3/4" piece of plywood underneath a phonebook that was a good inch-and-a-half thick.
Well.....needless to say the three sighting-in shots I took for grouping went through not only the phonebook AND plywood, but completely penetrated the door also...the three pellets (pointed game pellets) settling into one of my wife's favorite quilts (yes...I got my a$$ reamed-out, big-time).
Air rifles are NOT to be taken lightly...even the American versions. I think mine could kill a man if the pellet missed any major bone mass.
