  • How to determine scope height over bore for ballistics software

    1. Measure the bolt diameter and divide it in half. Example: 0.700″/ 2 = 0.350″

    2. Measure the scope tube diameter and divide it in half. Example: 1.000″ / 2 = 0.500″
    (Note: for 30mm tubes use 1.181, half of which is .5905")

    3. Measure the distance from the top of the bolt in the rifle to the bottom of the scope on the rifle. Example: 0.750″

    4. Add the numbers found in the formulas in steps 1-3. Example: (0.350″ + 0.500″ + 0.750″= 1.600″)

    It's knowing that when I get up in the morning and my feet hit the floor, the Devil says, "Shit! He's awake!"

    Shortly before World War I, the German Kaiser was the guest of the Swiss government to observe military maneuvers. The Kaiser asked a Swiss militiaman: "You are 500,000 and you shoot well, but if we attack with 1,000,000 men what will you do?" The soldier replied: "We will shoot twice and go home."
