I'm thinking about getting an air rifle that doesn't cost too much but isn't a piece of junk. I'd use it just for target shooting. The competitive events now have very expensive rifles. Well I'd like to shoot the 3 positions at 10 meters just using a reasonably price rifle and if I don't win- no problem. What are some choices for around $100 ish or less .177 caliber. Are bb's or .177 pellets used? Thanks.
