I had a look through a T50 recently and was not impressed with it's range finding at all, which is probably why you don't see any on the F.T circuit.
I had a MK1 BN which over-ranged by 7 yards whenever it felt like it. (The BN's are very variable and some are great)
I briefly had a Leup (not a comp) and it ranged my neighbours ridge tiles at different distances over and over again and those tiles were only 27 yards!! Nice glass though.
I now have two Sightron's and won't be selling them. Excellent scopes. The milldots are too big which upsets some people. And the Sightron scope covers are made by Fisher Price. Apart from that, I can't fault them.
