Greetings. I obtained a new Savage Axis .223 today. The barrel is stamped .223 of course. My question is will 5.56 work in this rifle? I've had other rifles that were 'marked' .223/5.56. I hesitate to use 5.56 in a barrel marked .223 rem until I can get a definite answer. Going to the range tomorrow to sight in the scope. From reviews I've read I think I'm going to like this rifle. Thanks.
