OK I'm not the best FT shooter by a good margin but I'm lucky enough to have a March X80 and a Mk3 Nikko.
I've had the Nikko around three years and the March about 12 months and to be totally honest although the image through the March is stunning I find the Nikko far easier to use and especially range find with. With the March I've found you have to be VERY careful ranging targets over 45 yards as its easy to get it wrong. As I've said I'm not one of the super shots and maybe it takes someone like Connor etc to get the best out of the March but for the average Joe the Nikko is all you need. Mine has been totally reliable and has only shifted once as far as I'm aware in 40deg temps. Put a 50 foot Leupold adaptor on it and you have a scope that will range from 7 yards to 55 yards accurately and consistently.
