marycat, the legal power limit in the UK is 12lb/ft
if you intend to take the rifle over that limit, you will need a FIRE ARMS CERTIFICATE. dont want to p*** on your parade, but what you are intending to do is (in the eyes of the law) exactly the same as owning a full power bullet gun !!!
there are a few air gunning forums if you look for them, but i honestly dont think anyone will give you detailed information in them.
12lb/ft is plenty enough for most people, me included. enjoy what you have before the laws are canged again, we may need to register ALL air guns if what im reading is true !
Fountain, it depends what type of gas cartridge it is. It's only the self-contained gas cartridge system that is banned like the '*******' system. This is because it can easily be converted to live ammunition. The type that is banned is here.
The legal limit for an air-rifle is 12 lb/ft but you have to remember that the grain (weight) of the pellet can affect whether your air-rifle can go over this limit. This means that if your rifle is close to the limit you have to be careful which pellets you use because it can easily go over the limit with the wrong pellet and a firearms certificate (FAC) will be required. A chronograph will record the exact lb/ft your rifle is capable of.
In your other post you mentioned that you wanted to kill rats/rabbits. A decent air-rifle just within the legal limit is adequate as long as you're a good shot and within a suitable distance from the target.
If you still want a higher output then you'll require a FAC.
