For sure it looks like it kills just as well or better than a 30-06.
your point?
There's no way. If you're only getting 2600fps from a 180gr bullet in a 30-06 then you are loading it light. When I used 180s in my 30-06 I got 2850fps chronoed and 2750 is easily doable. The 30-06 has heavier bullets and more frontal area than the 223 and will move them just as fast.
Here's a deer that was shot with a 180gr 30-06 by someone else.
That's a BIG exit.
Here's a hole in a deer shot with a 150gr 30-06 at 3000fps.
I'd like to see a 223 duplicate thoes.
