Long story, Rob.
I always fancied having a go at tuning an Oldschool HW50 after Jim showed his Venom tuned one in Airgunworld many years ago.
So I bought a nice HW50 off Mach 1.5 but it was a bit too good for me to mess about with, so I put that one in the gun cabinet.
Then I bought a HW99 stock off here from Rincewind.
Then I bought an action from Jonny Neate that he'd bought off the bay, but this turned out to have a buggered barrel.
Then I bought a HW99 barrel off someone at the Boinger Bash.
Then I bought another cheap HW50 off Mach 1.5 but decided to stick that one in the cabinet as well.
So I've now ended up with two HW50s and a big pile of HW50/99 parts to mess about with and put together, but that's a bit too easy so I'm aiming on stroking the poor little thing from 65mm up to 75mm to get her nearer to 12ftlbs for ratting duties.
All the best Mick
