For antipersonel use Black Hills 77 grain NATO loading from Georgia Precision. You will have no problem hitting chest-sized groups at 300 yards.

read the AR15.com Ammunition FAQ first.

It was the most useful information on ammunition I've come across so far. It answers all your questions along with explanations (why?) etc.

Just fine...

The M4 barrels are all 1:7

You only need a slower twist for 50gr or lighter ammo (eg 'V-Max' and such)...
