Yes Mark, hft Shooters maximum is 45yds but FT targets go out to 55yds and they use the bigger mag scopes to rangefind more precisely, that's why I was asking if the 30mag viper pro was good enough to recognise the different distances a couple of yards apart, last time I shot FT was a fair few years ago with a AIR ARMS PRO-TARGET with a 10-50x60 scope on top and that scope went in and out of focus at every yard or two at most, very precise but it was a huge scope.. and I like the idea of the rangefinding with the scope aswell, once its been setup...
