From what I've researched, a rifle chambered for 5.56 x 45 NATO can also safely shoot .223 Remington, but the accuracy when shooting .223 Rem may suffer. Has anyone verified this in their own rifle at the range?
Also, they say that if your rifle is chambered for only .223 Rem that using the 5.56 x 45 NATO round can be dangerous. My AR is chambered for the 5.56 x 45 NATO spec, but I'm wondering if accuracy will really be noticeably better using the NATO round vs. the .223 Rem.
