I have a small question myself in regards to a .223 vs. 5.56 NATO. Some people say that shooting 5.56 NATO out of a bolt-action rifle like the Rem. 700 chambered in .223 is not a good idea sense the 5.56 NATO is slightly more powerful then it’s civilian counter part the .223. Then I have also heard that it is ok to shoot either .223 or 5.56 from a good bolt-action rifle and it will not hurt anything. My youngest son and I would like to get a good bolt-action rifle chambered in .223 but we would like to be able to fire Mil. Surplus 5.56 without worrying that we me damage the rifle. We were thinking about the Rem. 700 in .223. Can this rifle handle the 5.56 NATO without any problems?
