Honestly I don't get it, unless you buy a suppressor and shoot subsonic ammunition it's just not any better than a 5.56 round as a hunting or SD cartridge. The folks in gun stores these days seem to still be in a swoon over the cartridge, especially guys under 35 or so. They piss all over the 5.56, and one today told me that the 5.56 was an answer to a question that was never asked and was a great "wounding" cartridge. His saving grace is he is well known as an opinionated ass but at the same time how can you not have enough brain cells to reconnoiter some elementary ballistics. Of course because he is so positive in his belief I am convinced the 5.56 won't kill stuff even though I have seen it with my own eyes. Wait till one of them puts a mag with 300's into their 5.56 and blows it up.
