This was my first bb/pellet gun I shot many a critter with it....
http://www.crosman.com/airguns/760B You can adjust the power of the gun by how many times you pump it. When I first got the gun I was only allowed to pump it five times, but as I showed my parents I was responsible I was able to pump it more and more times. This is a bb\pellet gun I have right now, It is a good gun as well....
