I am wanting to try a FFP scope. I have only used 10x scopes on my long range rig. First it was a SS10x42 then upgraded to a SS10x42HD. I love that scope but now want to try more magnification (I think anyway). I shoot a .308 out to 800 yards, have had to shoot 1000 but not very often. I have never felt like I need more magnification but think I would like it. So I am having trouble making up my mind. My SS 10x42HD I am moving to my AR15. So if I stay with 10x I want a ST10. If I go FFP I am looking at the SS5-20x50 and the Bushnell HDMR 3-21. So help me make up my mind. Stay with 10x and get the US ST10, or go to FFP and which one of the FFP's would you pick of the two I Talked about. I also want to stay around the 1500 dollar price.
