Sorry if this has been said before, but I don't have time to read 5 pages of comment.
I compete with military rifles and my AR-15 shoots 1" 5 shot groups at 100 yards. If anyone thinks these rifles are just a bullet hose, they are wrong. They are one of the most accurate rifles for competition in history. Don't believe me? Check out Camp Perry every year. If it is good enough for target work, it is good enough for hunting. I've met Jim Zumbo and can say I enjoy his mule deer experetise, but don't think he is very likable. Better not put him in any P/R job.
