ALG You are one of the lucky ones. As far as the Swaro's, you would have to ask S1. The Schmidts don't live on muzzle loaders, been there tried that. If you believe these scopes are so tough, why don't they dominate 50 bmg competitions where durability is a major issue?
The NXS has the finest Mil reticle on the market, it is called the MLR, and it does come with 1/10th mill knobs.
As far as first focal plane goes, why? If you have to turn the power down, whatever you are looking at is so close you don't need to range it to kill it. FFP is a bunch of Marketing hype. Never heard one experienced operator with 20 or more years in say, "Gee, its a good thing my optics were FFP.......or I'd have been FUBAR."
Never heard an experienced operator say, "in this situation, you need a FFP scope so you can perform X technique, picking up speed, accuracy, or both."
Guys can talk all they want about focal planes, but it makes no difference in the real world when it is time to kill, and you can bank that.
