When I was a lad my dad bought me a Relum Tornado, it was underpowered & no use for hunting, which was what I wanted it for, however it was incredibly accurate.

I used to shoot the heads off matches with it at what I'm sure was about 10 yards with open sights.

Certainly a modest springer & certainly very accurate, I've seen them come up for sale for 50 quid in good condition.
