There is a SFT class at all the BFTA GPs.
Yes you do have to be a member of a BFTA affilliated club.
When at the GP the person shooting SFT always shoots first so they cannot gain info about the range of the targets.
The max mag scope is 12x
Yes you can adjust your scope for each lane but not for each target (2 in a lane)
It's good fun
