Things I liked:I am very disappointed with the Gamo Whisper. I was unable to get a consistant shot group within 2 inches at 20 meters even afer 200 rounds. The rifle was anchored in shooting bags. I cleaned the barrel and still could not get an tight shot group. Seems as if rivets that hold the barrel in the stock might be moving providing an inconsistant aiming point. I fired expert in the US Army and have many years experience with rifles. I would not recommend the rifle to others based on my experience. I suspect I cannot return the rifle because my 30 days has elapsed.
