Just bought a LRP-07 and am trying to figure out which power glass to buy. I normally use NF 3.5-15X50 on 308's and am wondering if I should drop down to 2.5-10X42, never owned one of these. I'll be shooting out to 600-700 yards max and am setting this up as a multi purpose rifle for shooting 100 yards and out. Which one? Will the 10X42 go to 700 yards no problem?
