I have fired a few boxes of 223 American Eagle FMJ's with reasonably good results from my heavy barrel Ruger 77. I am curious if the gun could do better with something else. In most 308's I have owned, Federal Gold Metal Match with 168 gr Sierra Match Kings is a good base line. Can anyone recommend a 223 combo that works well in many guns? I am thinking about reloading, but want to establish a factory base line. Thanks.
