The Bisley mob do a vintage HFT every now and again. I was lucky enough to attend one of these once. They use pre war springers with open sights - most are 0.177 which surprised me.
I opted for a 0.22 and it was phenomenally good fun, the longest target was - I think - 42 yards. I aimed at the knot in the tree trunk about 2ft above the target and dang me - the thing fell over!
Most of the targets were somewhat closer and the scores were surprisingly high - mainly high forties.
I would thoroughly recommend having a go.
