There seems to be quite a bit of discussion regarding the differences between the 7.62 X 51 NATO and the 308 Winchester cartridges. My contention is the two cartridges are in fact one in the same. That is to say there is absolutely no difference in external case dimensions between the two. They are identical. My goal with this web page is to cover what I believe to be some of the myth surrounding the two cartridges. To make my point I'll use a few common tools and gauges common to rifle chambers. I will also use a few samples of actual ammunition.
