I used to have one of them, a weirauch 20. Had to sell it when I moved to Denmark. It was 'tuned up' a bit and I would need a permit to keep it as it was to powerful to be classed as an ordinary air rifle.Nice guns. I used to have quite a few PCP's but ended up selling all but one to fund other pew pews when I got my firearms licence.
The one I kept is a Weihrauch HW100.
Couldn't be chuffed at the time. But miss it now! Bloody pidgeons and hares just love my garden!
Mind you the last hare I saw in the garden was as big as a spaniel, so might need something a big more powerful lol.
