Yesterday I was out back and had both the Crosman Storm in .177 and the Titan in .22. I took the first tree-rat with the Titan one shot one kill which is the norm with this air rifle. A little later a few starlings showed up and the Storm preformed beautifuly three shots three dead. Had barely put the rifle down when Mr. Tree-rat comes down the phone line looking for a way in to the garage the storm got the call and sent a crosman domed pellet to the head of the little vermin, it was lights out. I went back to reading a hunting rag and finished a few articles and looked up, not one but two of the dreaded tree-rats were headed for the garage on the phone line well I was not having any of that, so I settled the little 2x7 Bushnell on the head of the lead rat and sent the crosman domed pellet his way he fell stone cold dead to the ground, but no time to celebrate, I cracked open the barrel and stuffed in another domed pellet the rat had turned and was moving away, as I settled the croshairs on his head he moved behind some leaves and small branches. I hesitated for a second, repositionded for a shoulder shot applied the presure to the trigger and at the impact the squirrel jumped a good 6 feet, but did not reach the tree he was trying for instead he was taking a permanent dirt nap. I went over and retrived my prizes and looked at the shoulder shot rat. Upon investigation I found that the pelled had broken the front leg taken out a rib, the left lung, heart and lodged in the right lung. Not bad for a cheap air gun.
