I have never shot FT, but I do shoot HFT and am a bit confused by this.

I've had a quick look at some rules and FT seems to be:
- smallest kill zone = 15mm to a maximum of 25 yards
- 25mm kill zones to a maximum of 35 yards
- all other kill zones between 40 and 45mm

HFT generally:
- 15mm kills to a maximum of 25 yards
- 25mm kills to a maximum of 35 yards
- maximum kill zone 45mm

(I've ignored positional shots obviously)

So apart from FT going out to 55 yards instead of HFT 45 yards. I can't see how someone with an HFT setup wouldn't do half bad. You just need to learn you extra aim points from 45 to 55y and then range find the same as you would round an HFT course, using holdover instead of adjusting scope (and learn to sit instead of go prone).

Am I way off the mark here? Like I said, I don't shoot FT
