First off Welcome , the search is still off due to programing problems . The 223 will shoot very well m you may want to look in the FAQs at the top of the page for lots of helpful info on getting the ,ost of your rifle . the most inportant thing is to make sure it is cleaned well , there is a lot of gunk and crud in it from the factory , most can not even be seen.
Try the Win. White Box 45 grain and the Rem 55 grain , these seem to shoot the best for fractory ammo . Hand loading can get it even better .
