BTW, I had the same problem, and since we have a "no firearm discharge" law within city limits, I went out to Academy and picked up a pellet rifle and a tin of 200 pellets. I spent two pellets fiddling with the sights, and 6 more on the family or tree rats in the tree in the front yard. No more problem. That was four years ago, and I still have 192 pellets.
