They are not part of the Bfta, so i dought there are many if any compition Ft shooters there, probably just some folk enjoying plinking.
I could be wrong about the members, but usually the better shooters are in clubs who compete in comps.
Try here

for a list of Bfta clubs. Lots of top FT shooters in these, should be something close to you?
