Re: March 1-10
I run a March 10-60x52 'tactical' model on my F-TR gun (I say tactical because that's what March call it, not what the application is). I shoot it on 20x mostly during our summers here, when temps get up to 105 - 120f and can successfully use it at about 40x in our winters, which are pretty light on compared to parts of the States. I only ever use the 60x when spotting for other shooters, so the extra 20x is a bit redundant.
What I can say about the March scope is that it tracks like it is on rails and the glass is on par with S&B, Premier and Zeiss Diavari (Same lens used in Hensoldt line), since I've owned all three. Subjective on the glass, I know but the mechanical tracking is extremely reliable. Mine is in 1/8th moa clicks but I think you can get most of them in 1/4s. If they did them in mils, with mils reticle, I'd definitely go for one for field shooting, as what surprised me most of all is that the scopes are actually quite rugged. I was expecting something more 'delicate' and was pleasantly surprised. Not as bomb-proof as an S&B or Premier in external engineering terms, or NF NXS - but probably a shade ahead of Leup MkIV, etc. Worth a look - but pricey.
