Anyone here have any experience with a short barreled .223AI? Considering building one in the 16-20" range for a nice, compact pack rifle. Anyone have any idea what kind of velocity could be expected with a 75gr ELD?

I would think that a 20"barrel should come in around 2750 to 2800 ft/sec.

I'm running 18" but with lighter bullets. Seems like there is more gain with lighter bullets and it diminishes as you go heavy. Oh ya 53gr vmax 3394fps
Have you ever run heavier bullets out of it? It just seems like you should be able to hit around 2900 with a 75gr bullet out of a 20" barrel since there are factory 5.56 loads doing it. I would think a 223AI should at least keep up with the higher pressure NATO round given the increased case capacity. Maybe I'm mistaken though, hence the post.
