*old thread but best I could find on the search function for my question*

For a short action hunting rifle similar to the GAP NT setup to 600 yards for stand hunting whitetails (fields, cuts, roads, etc), spot and stalk mulies and antelope, I am debating between the fixed 10 S&B, and a NF 2.5-10x42 or NF 4-14x42. I have never considered the fixed 10 but see that it gets great reviews so I am asking for your thoughts on my choice. What am I gaining or losing with those choices? The cartridge will probably be a 6.5mm of some sort or a 7mm-08.
