Well, high fence doesn't mean squat if the pasture is a couple of thousand acres or more--which is the most common. I could high-fence the 100 acres of my southeast pasture and the only way you'd see a deer would be if he stood on his hind legs and waved at you.
But, since the subject of the thread is rifles, I guess the consensus seems to be that they don't really discuss rifles and cartridges all that much.
