Get a 40gr V-Max or better yet Z-Max shooting at about 3500 out of it. Goes in, Blows up, never comes out
Yeppers.
I built a bull barrel AR in 204 specifically for this task. Very fast and does not exit. I shoot the 26 and 32 grainers in the 204. The 40 should be dandy in the 223
I have no idea what the hell I am doing.
So I just keep shooting. It all works out in the end.
