Light gathering comparison?
Buddy of mine currently shoots a Leupold 6.5-20 and isn't crazy about the low light performance of it. He's getting ready to build his son a 300 Ultra and asked me about scopes. I've read a lot of good stuff about the Sightron S3 and was wondering how it compares in low light to a Leupold, NF, or other top scopes. Thanks
