It’s been gratifying the last few years to see the increased popularity of the kind of medium-power scopes that he talks about. I lucked onto leupold’s 1-4X shotgun scope 20 years or more ago, and it and its cousins have become my go-to scopes for a whole lot of things; from AR carbines to handgun-caliber carbines to 22 rimfire. Big, big fan of that type of scope.
I used to have really good eyes; 20/15 back in the 70's. But now, I can't shoot reliably more than a couple hundred yards with open sights, and even then probably not on targets less than 16"-18" in size.
