Except Elmer derided all open sights on rifles (see BIG GAME RIFLES). His famous 44 Magnum kill of the wounded deer could have been done in one shot had his S&W been scoped.

Back in the day there were globe front sights housing a fine vertical wire with 3 dots affixed to it. Worked like a bow sight. You selected which bead to use and placed it in the center of the aperture or the notch of an open sight. Far better than "Kaintuckie" elevation guesses. Some handgun front sights replicate this idea with horizontal gold lines. Better than a swag.
