I'm looking at purchasing a Sightron SIII Precision Long Range scope for use on my Seekins Havak Bravo in 6.5CM. I will be shooting it from 100 to 1000 yards and looking at either the 8x32x56 or 10x50x60 models. My question does the 10x50 really provide any advantage over the 8x32 power for this shooting? My Seekins does have a 20 MOA rail to provide me with more elevation.
