More from nostalgia than necessity, a few months ago I bought a .177 Weihrauch Hw35 off an airgun forum. It's a lovely gun, but bloody heavy! It was the gun I aspired to in the late '70s when I had a BSA Mercury .177. I keep meaning to get some different front sight inserts, as the one I have is rather too thick.
When I lived in Sweden, I harboured a desire to buy a .30 air rifle there and bring it back in the car, but if I'd been caught, I'd've been in deep shit, it being a firearm at that kinetic energy. (Those days, the Swedes categorised rifles by muzzle velocity, not kinetic energy - apprently.)
