Bring your rig to the south west and take part in our HFT comps. Our rules are quite similar to the old SFT rules. You can adjust the scope for each target before you look through it. And you can sit on a cushion for the freestyle lanes. You do have to touch the post, and keep below 12 mag.
We have a category for spring guns in HFT which is separate from the PCPs so you would be competing like for like with others.
I'm sure one of the south west clubs would be happy to accept you as a country member.
