Airguns are cool.
The British put out the best airgun magazines (reading kind) in the business. Well worth looking for at your local book store.
Unfortunately for the Brits, it seems many of their air guns are restricted in power.
I have one PCP, a Hammerli Pneuma. It is out of commission at the moment, two air cylinders that will not hold air. I've had it more then 10 years, it was fun to shoot for a while. I chroned it (forgot to write down the pellet gr. size at an average of 1054fps .22 caliber.
When I take an airgun to the range these days I shoot an RWS 56TH in .22. It's a side lever spring powered single shot. Chrony had pellets 14.3 grains averaging 866 fps. Best group of 5 shots at 25 yards .567".
I was able to break a clay pigeon mounted on the target board at 100 yards after taking several shots with the TH.
