40 targets would be nice, but I understand the negative side of longer time to shoot.
There are a couple of potential solutions to this:
1, Compulsary timing, 45 seconds to take the shot from scope to the eye. (based on FT use 2 mins per lane -1 min per target- but no rangefinding in HFT so it must be worth 15 seconds)
2, Make shooters stick to a certain order per lane instead of standing debating "is it me..... is it you..... is it my uncles aunt fanny" etc
Far too much fannying about by some. There is no advantage shooting 1st, 2nd 3rd or whatever - you all get a shot at the bloomin target.
