As much as I can see the benefit for shooters shooting abroad to have a meter range and wheel setup, i'm not seeing a need for it in the UK... and as someone once said, if it ranges Cherry, then you dial Cherry...
Probably the biggest hassle for UK shooters abroad is checking rangefinding, but 50m is near enough 55 yds as to make no difference. Just remember 1m = 1.1yd So if you're ranging on a 30m board then it should read 33yds.
