Have a few questions for the experts. I was brought up around guns of all kinds. My father was a big outdoorsman and taught me a lot. But recently, I'm trying to get into the "Long Range Accuracy" side of shooting. My top 3 questions. 1. What's the definition of a "Fully Floated Barrel" and what are the Pros for having one.? 2. I've seen a few friends while shooting, place 1-2 fingers on the barrel but have always been taught not to. Which is right or wrong.? 3. Is it a method to use when sighting in a rifle to get something and tap the scope after adjustments to make sure reticle moved.? Thanks guys. Oh, Lehman's terms please.
