Thread: Favourite 223 bullets for game?

Having recently acquired a 223 and deciding what to feed it, I thought it would be interesting to find out what projectiles you clever folk prefer to poke holes in medium sized animals with.

In my case it won't be a primary deer rifle, more for goats and wallabies (though the capacity to take deer as well is useful). And 1:9 twist so it should be happier with heavier rounds, but with all the different bullet designs it would be good to learn what people have found most effective for NZ hunting.
