Greetings & Welcomes.
As Simon says, once you know where your nearest club/shoot is, get thi'sen down there and you'll get plenty of tips and advice. DO NOT go spending until you know what discipline you would like to shoot and have had the opportunity to try some hardware. Air rifles are fit > function.
