    does anyone have a link to ballistic info for M193 and M855 loads over distance... fps/energy/drop/yds etc.

    ?

    I have a ballistics app.

    If I could get the screen shots added you would have all the info your heart desires....

    well.... Im just curious about M193 and M855 or do they make those in different weights? Im assuming not...

    or is this top secret gubermint data? I find it interesting the ammo is so readily available but no info on it.

    55gr and 62.
    I didn't know if you had other weights as well. Nothing secret.

    Know:
    Velocity
    BC
    Bullet weight

    And you can calculate the drop/energy easily.


    M855:
    3025
    .158 BC
    62gr

    5.56/55gr/193
    3240
    .269 BC
    55gr

    62gr 5.56
    3020
    .307 BC
    62gr

    at what distance?

    and I dont know any of that info. The websites that sell it sometimes list a muzzle velocity... which can be different between websites.

    Im looking for something like the way most ammo manufacturers chart out their ballistic data over distance, usually up to 500 yds. Hornandy does this for one 5.56 load but its not NATO spec... http://www.hornady.com/store/5.56-NATO-55-GR-GMX-Superformance/

    more info than I can shake a stick at... :cool:

    so if I read that right M193 drops -2.8" at 200yds, 2472fps, 746ftlbs with a 100yd zero...

    Yes... And 'no'

    This all assumed a 1.5" sight height as well. If you get me your actual sight height from centerline of bore to center of sight I can punch in the actual data for your rifle.

    You will be close +\- .75" more or less as well depending on barrel and your actual velocity.

    Know your actual velocity? Can punch that in and you will know exactly what your rifle will do.

    All generics at this point but it's close.

    I have no way of measuring my actual velocity.

    I think what you gave will be close enough... I just wanted to compare the nato loads to other factory loads (incl. 223).

    Anyone use JBM's free online ballistic calculator?

    I crono my guns for the best info available. Then plug in the needed info. It's a good starting point before any real world variables.

    You could start with standard barrel length velocities and be in the ball park I guess? :s0092:
