A few years ago I shot a round of the midlands HFT with johnny smith who shot a .22 daystate.
It interested me how much johnny had to think about each target. Such that I was inspired to have a go. In December I picked up an Air Ranger in .22 and it is a pleasure to shoot.
I think that .22 offers a challenge for any course and if you fancy a change it's worth a go. I think a shooter of your standard may well attract others to have a go
