OK , so here's the question : If I take an 8-32X 56 Sightron S III , Nightforce BR 8-32X 56 , and a LR Leupold 8.5- 25X 50 out to the Prairie Dog Fields on a nice sunny day , and set all three at 25X , how much difference in Optical Resolution / Sharpness am I going to see ??? ..... a whole lot , some , not much , or none ??? It would also be useful if you rated them in order . TIA .
