I've got a NF 5-25 F1 in a 20 MOA SPUHR mount, on a 20 MOA base. Being able to dial out to a mile with a 308 Winchester is nice. The only thing I haven't tested yet is whether or not having your erector (not sure is correct term) set that far from center effects optical performance. There has been a time or two where my reticle went fuzzy, not sure if it was my eyes, diopter, or a side effect of the scope being near it limit of travel.
