    AR10/M1A1 ballistics comparison?

    Does anyone know where a guy can fnd some ballistics data from these guns, with hopefully the same or very similar round? Also looking for MOA accuracy info for both of these rifles, as shipped from the factory.

    *note: The M1A1 is the civvie version of the M14, right?

    The difference in ballistics between the two will be a function of barrel length, so it depends on what length barrel you go with. Accuracy will depend on the model. An AR10 will tend to be more accurate than a bare bones M1A, but the M1A can be made to be as accurate (higher end models and/or tuning).

    And yes the M1A is a semi-auto verion of the M14.

    +1 MOA will depend on what you get and who you get it from. (Basically how much you spend). Ballistics is a function of the velocity, bullet, and rifling. If they have the same rate of twist and same length barrel, chances are good the velocity will be quite similar. So ballistics will be pretty much the same.

    I have a DPMS AR 10 with a 24" match barrel. It will shoot 1/3 MOA when I do my part. Of course, knowing what I know NOW, I'd have bought the 16" model and not needed a fork truck to move it off the bench.

    That was my next question. What barrel lenghts are typical and what are ballistics like out of the shorter barrels. (drop and energy every 100 yards or so?)

    I did the same thing when I got my first one. The new one w/ the 16' barrel is actually something I could carry for a while! The iron sights on 'er are great...looking for something snazzy to drop some cash on now...EOTech or something...

    Well, there doesn't seem to be much comparison...one fires a 7.62mm cartridge, the other a 120mm HE shell or sabot:

    I dont figure that a few inches either way matters much with that HE round...
