Anyone got ballistics table for M193 from a 16" M4 barrel out to 500 meters/yards?

thanks for the pic, but This looks like its from a 20 inch barrel. I have the same tables and mine says its from a standard 20 inch barrel.

True military spec M193 tends to run around 3100 fps from a 16" NATO chambered barrel. Since you didn't give any specifics about the ammunition you are using I used a generic muzzle velocity of 3000 fps for the calculations. If you have some chronograph data from the ammo you are using with the specific ballistic coefficient of the bullet you are using I'd be happy to run the calculations again for you.

I was using Oehler Ballistic Explorer and did some calculations on a regular m193 with muzzle velocity of 3250 fps from a 20 inch barrel with sight height of 2.6" no windgust zeroed @ 25 meters and the calculations came up different from the military's calculations. Oehler Ballistic Explorer m193 calculation dropped 3.5" @ 300 meters, and the military calculation drops .4" @ 300 meters. Who is accurate on calculations?
