what velocity you get from 75g 223 in 16" barrel?

    curious what you're getting.

    i'm near max load, which is supposed to be 2900+ and my chrono today showed 2500 average, which is less than the starting load is supposed to give.

    granted, i'm sure the manual wasn't testing with a 16" barrel, but still, i think i'm getting shorted at least 200 fps :(

    I found the same thing, when I loaded some 60 gr. Noslers out of a 16", I only got a fuzz over 2600 fps with a heavy dose of RL15. I was disappointed too as the book said 3000+ fps. Those 16" barrels play hard with velocity.

    I ran 5 shots of 75 grain Hornady Tap factory loads thru my Pact chronograph using a 16" Colt came up with 2543 FPS average on a cool day around high 50s - low 60s . Disappointing for sure.

    well, they still shoot well. reasonably accurate, but that velocity is disappointing. iirc, i push the 80g faster than that in my 600yrd line loads

    Remember that most velocities are listed with a 24" barrel. 8" less barrel and you have 1/3 less length for the bullet to be accelerated.

    I am playing around with some lighter bullets now and seeing allot of promise there. If you aren't shooting long range it might be an avenue to try.
