Need help deciding on my first air rifle....

All PCP guns will leak their pressure tank, sometime. AIRguns are not a safe or practical tool for any defence situation. +1 to the above.

Try reading the hunting forum and the big bore forum. Every gun under the sun has been discussed and you will find that you accidentally learn a lot more than you thought you would.

Cheers.

Time change got me. +1 to the below comment....
