I ran those big HP 75 grainers in my #1B .243 win on chucks for over a decade. I had two kick up dust 10 yards or so past the body hit chuck.
Other blew inside wo exit. Some blew massive exit holes but were fragmented such nothing kicked up beyond.
I would not run them on anything but varmints at top V.
Dunno how lesser zip ( 6mm 223 ) might affect explosive nature of that bullet.
Our bucks run 150-200 lbs dressed.
Not huge but not small.
