It's a seperate discipline we shoot down at Ford Ranges, and I know that Lea Valley have been doing dedicated pistol HFT competitions each month for longer than Ford, so there are clubs out there which cater specifically for this. Targets are generally not more than 35 yards and are specifically lightened in sensitivity so they'll drop with less power required. It does mean that you need a seperate set of targets for pistol comps though.
