I think AG was trying to say what a decent buy that set up is It would absolutely be cock on as a HFT/hunting rig and was my choice when rook shooting over the last few years. My mate cleared a HFT course with a HW100.
Just verify how much test the bottle has and whether it's 300bar and if you have the chance try and get the seller to let you shoot a full fill through the rifle to make sure it groups well.
