    hensoldt rf reticle

    hensoldt rf reticle OK. It's pretty simple. The reticle is used to measure angles and the unit is milliradians, i.e. 1/1000 of a radian. You might know the relationship between angle, radius and length of arc when using radians but if you don't then here it is: angle = length of arc / radius...

    What is it that you don't understand? It's like a mildot reticle.

    Mil value changes with range? How do you use it?

    To me it sounds like you have not grasped the basics for measuring angles with radians. It's really simple. Angle (in radians) = length of arc / radius of arc. At small angles you can say that the linear distance is equal to length of arc. For us shooters that means that the formula is angle =...

    Advanced Marksmanship My Mil formula for distance in yards

    My Mil formula for distance in yards Why not use target size in yards? Target size in yards / size of targets in mils x 1000 = range in yards And the answer is?.......somebody messed up the relationship between inches and yards. And the solution is?.......the metric system!! Target size...

    CM, Mill, and Cant

    mrad, milliradians, has nothing to do with meters, yards or whetever length or distance. It's an angle and it is one thousand of a radian. The formula is really simple: angle (in radians)= length of arc / radius. So just multiply the distance (radius) with the angle and you get a very good...

    Bullet drop to mil confusion

    Russia and Finland: 6000 Sweden: 6300 before 2007 but now we use mils in Sweden, i.e. 6400.

    .20-.22LR Super Stinger

    .20-.22LR Super Stinger What about your idea to measure pressure by recording sound levels? Is this something you believe will work?

    Advanced Marksmanship Shooting from a moving plattform! Maritime sniping.

    If you exclude the wind caused by your moving platform then you can calculate the lead by using the formula for a moving target and stationary gun. To that you would have to add the effect of the virtual wind caused by the moving platform. The movement of the platform will require less lead no...

    .20-.22LR Super Stinger

    Fred, I strongly doubt that measuring sound levels will tell you anything about the peak pressure. Muzzle exit pressure maybe but not chamber pressure. A strain gauge on the barrel mounted at the origin of rifling is a much better method.

    Gunsmithing Alright I am flat stuck!!!

    First post for me. You say you have Millet rings? If that is Angle Loc, look no further.
